INSTALLATION GUIDELINES
This Module is suitable for mounting on 35mm DIN Rail. Note the polarity when connect field wire. The (horizontal) mounting arrangements shown here, allows good vertical air circulation. It is also recommended to keep adequate gap between two modules.
- Size: 225.00mm X 90.00mm
- Figure1: Mechanical & Mounting with Nomenclature
Before wiring, verify the label for correct model no. and options. Wiring must be suitable for voltage, Current and Temp. rating of the system. Verify that the ratings of the o/p & i/p as specified.

CONFIGURATION AND TERMINAL CONNECTION DETAIL
CONFIGURATION
Linearized RTD/TC module is configurable through configuration software “mTRAN”. Configuration and calibration should be done in non hazardous area. Once configuration is done, parameters are changed.
Guidelines for Configuration Software mTRAN version 1.0.1.1
Before making a configuration of module you need to do following:
- Install the drivers for the USB Interface.
- Install the PC configuration software mTRAN in your PC.
Please refer to configuration software manual “m10/om/202” for software and USB driver installation. All software and manuals are included with module, and can also be downloaded from the web site.
Configuration procedure:
- Connect the module to the PC via the USB Interface.
- In configuration software four modes are available.
- Run mode
- Configuration mode
- Calibration mode
- About us
- Run Mode displays process values, Input Types, Range High, Range Low, Ambient Temperature, Start and stop communication buttons are available in the screen. And User Can Start/Stop communication and select the COM Port from any window.

The 8 Channel RTD/TC modules are used in applications like industrial process control, Factory automation, SCADA and DAS.
TROUBLESHOOTING
- Unit not turning on
If RED LED on the module is ON then problem can be bad connection or due to incorrect rating of power, fuse blows.
If GREEN LED on the module is ON, it indicates the module is in healthy condition. - Unstable reading
Check for loose connections.
First verify that all conventional instrumentation norms have been followed for wiring. Make noise away from the module. Check for ripple on power supplies of Input & Output section sections. - Output not matching with the expected value.
Kindly make sure that the output is really incorrect with respect to input signal, before attempting any re-calibration.
