Temperature Monitoring module
The module, occupying a single slot, monitors four channels of temperature inputs.
As input conditions and other data that are needed for temperature monitoring are stored in the module, no parameter setup is required at system startup.
Details
Features
- High accuracy, high resolution, high speed
The input sampling period may be selected from 10ms, 100ms, or 200ms. The input conversion accuracy is ±0.1% of full scale, and the input resolution is 0.1℃ (using 5-digit representation). Low-resolution operation (using 4-digit representation) is also available. - Universal input
The input type may be set to thermocouple, RTD, or DC voltage for each channel. - ToolBox for Temperature Monitoring Modules
A dedicated ToolBox software is provided for this module. With this software, you can easily set up various parameters of the module and monitoring by following screen instructions.

*1 : You can select an input sampling period of 10 ms for 4 channels, 100 ms for 2 channels, 100 ms for 4 channels, or 200 ms for 4 channels.
*2 : This value assumes that all input terminals are correctly wired (that is, using ferrule, wire diameters and connections are correct).
*3 : This value assumes that the power supply frequency is correctly selected.
*4 : This module continues to operate at a input accuracy of ±0.5% max. of F.S. during the radiated electromagnetic field test.
*5 : This is the value when an input sampling period of 100ms or 200ms is selected. If 10ms is selected, 50/60 Hz noise canceling is not be enabled.
