订购热线：TC Input/RTD Input Module (Isolated Channels)
These modules receive signals from mV, thermocouple (TC), RTD, and potentiometer (POT). These are isolated between the field and the system as well as between each channel.
They can be used in dual redundant configuration.
These two modules can be used in dual redundant configuration.

*1: Model AAT145 is also in compliance with JIS C1602:1981.
*2: Type B dose not carry out temperature compensation and can not measure under 44 °C.
*3: Model AAR145 is also in compliance with JIS C1604:1989 (Pt100, JPt100).
*4: Wiring resistance for the signal cables of IN£A and IN£B must be identical.
*5: This accuracy changes due to the installation condition.
If measured temperature is lower than 0 °C, multiply the above value by the following coefficient (K):
Thermoelectromotive force per degree at 0 °C
Thermoelectromotive force per degree at measured temperature
F05E.ai
*6: Reference junction compensation accuracy varies depending on the temperature environment of terminal board (AET4D).
