This transmitter is designed for mounting in DIN Form B connection/sensor

heads commonly used in thermowell applications for sensing temperature or

for use in an enclosure with suitable strength and rigidity. Optionally, a DIN-

rail adapter may be purchased for mounting the unit to T-type, or G-type

DIN rail. The transmitter must be installed in an ATEX Certified enclosure

with a minimum ingress protection rating of at least IP54. Enclosure must

have a door or cover accessible only by the use of a tool (See page 28 for

details).

Its non-isolated input is intended to mate with non-grounded, type J, K, T, R,

S, E, B, & N thermocouple temperature probes common to these thermowell

applications. It provides an output current linearized to the TC sensor

temperature. Optionally, it can support simple millivolt inputs and drive an

output current linear to the voltage.

The output signal is transmitted via a two-wire, 4-20mA current loop. The

two-wire current signal can be transmitted over long distances with high

noise immunity. Sensor lead-break detection and the inherent live-zero

output offset offers convenient I/O fault detection, should an I/O wire break.

WARNING –EXPLOSION HAZARD –Do not disconnect equipment unless

power has been removed or the area is known to be non-hazardous.

WARNING –EXPLOSION HAZARD –Substitution of any components may

impair suitability for Class I, Division 2.

WARNING –EXPLOSION HAZARD –The area must be known to be non-

hazardous before servicing/replacing the unit and before installing.

Wire terminals can accommodate 14-28 AWG (2.08-0.081mm2) solid or

stranded wire. Input wiring may be shielded or unshielded twisted type.

Ideally, output wires should be twisted pair. Strip back wire insulation 3/8-

inch on each lead and wrap the bare wire in a clockwise direction around

the terminal screw and below the SEMS washer. Tighten the screw to

secure the wire at a torque rating range of 0.226 to 0.282 N-m. Terminals

include wire loops for test clip attachment, or for redundant soldered wire

connection required for heavy shock and vibration applications. Since

common mode voltages can exist on signal wiring, adequate wire insulation

should be used, and proper wiring practices followed. Output wires are

normally separated from input wiring for safety, as well as for low noise

pickup. Cables and/or conductors in conduit must have a minimum

temperature rating of 110°C.

Sensor wires are passed up through the center of the transmitter and wire

directly to transmitter input terminals 2 and 3, as shown in the connection

drawings below. Observe proper polarity when making input connections.

•Use Insulated or Non-Grounded Sensors Only - Input is non-isolated.

Do not ground any input leads.

This transmitter has an ANSI/ISA Type 2 output in which the power and

output signal share the same two leads, and the transmitter has a floating

connection with respect to earth ground. In these applications, output wires

normally pass through the output channel on top of the transmitter and are

drawn through the egress path of the connection head. Connect a DC

power supply and load in series in the two-wire loop as shown in the

drawing below.

•Output connections are not polarized. The + and –designations are for

reference only with current normally input to Output+ and returned via

Output-.

•Loop supply voltage should be from 7-32V DC with the minimum level

set to supply over-range current to the load, plus 7V across the

transmitter, plus any transmission line drop.

•Variations in power supply voltage between the minimum required and

32V maximum, has negligible effect on transmitter accuracy.

•Variations in load resistance has negligible effect on output accuracy as

long as the loop supply voltage is set accordingly.

•Note the placement of earth ground in the current loop. This is very

important when making a connection to USB and will drive the need for

USB isolation (see below).

•Always connect the output/power wires and apply loop power before

connecting the unit to USB.

The output of this transmitter has a floating connection relative to ground

which makes it flexible in the way it connects to various “Receiver” devices.

In most installations, the loop power supply will be local to either the

transmitter, or local to the remote receiver. Shielded twisted pair wiring is

often used to connect the longest distance between the field transmitter and

remote receiver. The receiver device is commonly the input channel of a

Programmable Logic Controller (PLC), a Digital Control System (DCS), or a

panel meter. Some receivers already provide excitation for the transmitter

and these are referred to as “sourcing” inputs. Other receivers that do not

provide excitation are referred to as “sinking” inputs, and these will require

that a separate power supply connect in the loop.

Here are example transmitter connection diagrams for “sourcing” and

“sinking” receiver types:

WARNING: For compliance to applicable safety and performance

standards, the use of twisted pair output wiring is recommended. Failure

to adhere to sound wiring and grounding practices as instructed may

compromise safety, performance, and possibly damage the unit.

TIP - Ripple & Noise: Power supply ripple at 60Hz/120Hz is normally

reduced at the load by the transmitter, but additional filtering at the load can

reduce the ripple further. For large 60Hz supply ripple, connect an external

1uF or larger capacitor directly across the load to reduce excessive ripple.

For sensitive applications with high-speed acquisition at the load, high

frequency noise may be reduced by placing a 0.1uF capacitor directly

across the load.

TIP - Inductive Loads: If the two-wire current loop includes a highly

inductive load (such as an I/P current-to-pressure transducer), this may

reduce output stability. In this case, place a 0.1uF capacitor directly across

the inductive load and this will typically cure the problem.

The unit housing is plastic and does not require an earth ground connection.

If the transmitter is mounted in a metal housing, a ground wire connection is

typically required, and you should connect the metal enclosure’s ground

terminal (green screw) to earth ground using suitable wire per applicable

codes. See the Electrical Connections Drawing for Output/Power and note

the traditional position of earth ground for the two-wire output current loop.

The Type II transmitter output terminals have a floating connection relative

to earth ground. Earth ground is normally applied at the output loop power

minus terminal and in common with the loop load or loop receiver minus.

•Do not earth ground any input lead and use only insulated/non-

grounded TC sensors. This transmitter does not isolate its input signal.

•Respect the traditional position of earth ground in a two-wire current

loop and avoid inadvertent connections to earth ground at other points,

which would drive ground loops and negatively affect operation. This

includes the USB connection to the transmitter, which should be made

via a USB isolator, as most Personal Computers earth ground their USB

ports, and this makes contact with both the signal and shield grounds.

This transmitter is setup, configured, and calibrated via configuration

software that runs on a Windows-based PC that is connected to the unit via

USB. Refer to the drawing below to connect your PC or laptop to the

transmitter for the purpose of reconfiguration and calibration using this

software.

WARNING –USB Connector is not for operational or maintenance use

in hazardous locations. The intent of mating USB with this transmitter is

so that it can be conveniently setup and calibrated in a safe area, then

installed in its connection head, which may be in a hazardous area. Do not

attempt to connect a PC or laptop to this unit while installed in a hazardous

environment, as USB energy levels could ignite explosive gases or particles

in the air.

•USB Signal Isolation Required (See Below) - You may use Acromag

model USB-ISOLATOR to isolate your USB port, or you can optionally

use another USB signal isolator that supports USB Full Speed operation

(12Mbps).

•Configuration Requires USB and Loop Power - This transmitter

draws power from both the current loop and from USB during setup.

•Connect Loop Power Before USB - Always connect the transmitter to

its loop power supply before connecting USB, or erratic operation may

result.

IMPORTANT: All USB logic signals to the transmitter are referenced to the

potential of its internal signal ground. This internal ground is held in

common with the USB ground and shield ground. The potential of the

transmitter’s current output pin (output minus) relative to earth ground will

vary according to the load current and load resistance (net IR drop).

Without isolation, this IR voltage drop would drive a potential difference

between the normally grounded current loop and the grounded USB

connection at the PC, causing a ground loop that would inhibit setup and

calibration, and may even damage the transmitter. This is why an isolated

USB connection is recommended. You could alternately avoid the use of an

isolator if a battery powered laptop was used to connect to the transmitter,

and the laptop has no other earth ground connection.
