(2 points, isolated) MODEL R30US2
BEFORE USE ....
Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.
■PACKAGE INCLUDES:
Universal input module (body + CJC sensor × 2)..............(1)
■MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■CONFORMITY WITH EU DIRECTIVES
• The equipment must be mounted inside the instrument
panel of a metal enclosure.
• The actual installation environments such as panel con-
figurations, connected devices, connected wires, may af-
fect the protection level of this unit when it is integrated
in a panel system. The user may have to review the CE
requirements in regard to the whole system and employ
additional protective measures to ensure the CE conform-
ity.
■GENERAL PRECAUTIONS
• Before you remove the terminal block or mount it, turn off
input signals for safety.
■HOT SWAPPABLE MODULES
• It is possible to replace a module with the power supplied
provided that the module is replaced with one with the
same model number and installed in the same base slot.
• Turn off input signals before replacing the module for
safety. Note that replacing multiple modules at once may
greatly change line voltage levels. We highly recommend
to replace them one by one.
■UNUSED CHANNEL
• Set unused channels to “CH disabled” with PC Configura-
tor software (model: R30CFG). Otherwise, unused chan-
nels left open are to be burnout status, setting a data er-
ror at the PLC or other host devices.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within -10 to +55°C
(14 to 131°F) with relative humidity within 10 to 90% RH
in order to ensure adequate life span and operation.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
• Be sure to attach the terminal cover for safety.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

INSTALLATION
■INSTALLATION TO THE BASE
Use the Installation Base (model: R30BS).
The I/O slots are numbered in the ascending order starting
from the one on the immediate right side of the network
module (slot 1, slot 2...).
A code indicating the I/O slot number is assigned to each
I/O slot and I/O data is allocated in the order of this codes.
When an I/O slot is vacant, blank data is sent or received to/
from the PLC, etc.
PWR COM I/O1 I/O n
■HOW TO MOUNT THE MODULE
1) Engage the positioning guide of the module with the In-
stallation Base.
2) Pivot the module on the positioning guide and press it
down until the lock tab clicks into place.
Positioning Guide
3) Tighten the base fixing screw using a screwdriver (stem
length: 70 mm/2.76” or more) (torque 0.5 N·m).
