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.

■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
■HOT SWAPPABLE MODULES
• Replacing the module does not affect other modules on
the same base. Thus, the module can be replaced while
the power is ON. However, replacing multiple modules
at once may greatly change live voltage levels. We highly
recommend to replace them one by one.
■GENERAL PRECAUTIONS
• DO NOT set the switches on the module while the power
is supplied. The switches are used only for maintenance
without the power.
■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 30 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.
■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
Use the Installation Base (model: R3-BSx).

INPUT DATA DESCRIPTIONS
■ANALOG DATA (TEMPERATURE DATA)
16-bit binary data.
With °C temperature unit, raw data is multiplied by 100. For example, 25.5°C is converted into 2550.
With °F temperature unit, raw data is multiplied by 10. For example, 135.4°F is converted into 1354.
Minus temperature is converted into negative values, represented in 2’s complements.

Unused channels left open are equal to the burnout, which
turns the red ERR LED on and sets a burnout flag at the
PLC or the host device.
Unused channels can be specified and set so on the PC Con-
figurator Software (model: R3CON) without needing to con-
nect resistors at the field terminals.
