The ELCM-TC04ANNN temperature measurement module supports 4

channels of thermocouple temperature sensors (J-type, K-type, R-type,

S-type, T-type, E-type, N-type, ±80mV) and converts these signals into

16-bit digital data. You can select temperatures in Celsius (resolution: 0.1°C)

or Fahrenheit (resolution: 0.1°F). The data in the module may be accesses

using the FROM/TO instructions, or you may read the average value of

channels directly by using the MOV instruction (Please refer to allocation of

special registers D9900 ~ D9999).

This instruction sheet provides only information on the electrical

specification, general functions, installation and wiring. It should be read

and understood before attempting to install or use the module.

Further information can be found in the “ELC Programming Manual” and

“ELC Special Modules Operation Manual”.

This module is a part of an OPEN TYPE control system. The ELCM

should be kept in an enclosure away from airborne dust, humidity,

electric shock risk and vibration. Your application may require that the

enclosure be locked to prevent non-maintenance staff from operating the

controller (e.g. key or specific tools that are required for opening the

enclosure) in cases where danger and damage to equipment or

personnel may occur. Do NOT touch the terminals while power is

applied.

DO NOT connect AC input power to any of the input terminals; otherwise

serious damage may occur. Check all the wiring before switching on the

power.

Ensure that the ground terminal is properly grounded in order to

prevent electromagnetic interference

This manual is subject to change without notice.

Note 1: Use cables specifically designed for use with thermocouple temperature sensor J-type,

K-type, R-type, S-type, T-type, E-type and N-type, or use double shielded cables to

minimize the effects of noise. Temperature inputs should be separated from power cable

or other wiring that may cause interference.

Note 2: Connect the terminal on both power supply and the ELCM-TC04ANNN to a

proper system ground.

Explanation on Special Registers D9900~D9999

When ELCM-PH/ELCM-PA controllers use expansion I/O modules,

registers D9900~D9999 will be reserved for storing values from these

modules. You can apply the MOV instruction to access values in

D9900~D9999.

- 7 -

When ELCM-PH/ELCM-PA controllers use the ELCM-TC04ANNN, special

registers are configured as shown below:

Note 1: D9900 ~ D9999 are average input values of CH1 ~ CH4 and the average times is K1 ~

K100. When the average times is set to K1, the values displayed in D9900~D9999 are

current values. You can use: 1. ELCM_AIO Configuration Function of ELCSoft or 2.

FROM/TO instructions (CR#8 ~ CR#11) to set the average times as K1.

Adjust TC Conversion Curve

You can adjust the conversion curves according to your actual needs by

changing the Offset value (CR#28 ~ CR#31).

Offset in ELCM-TC04ANNN: Deviation digital value from the target value.
