AAR145-S50 Yokogawa, TC/RTD Input Modules (Isolated Channels)

Description:

AAR145-S50 is a TC/RTD Input Modules (Isolated Channels), manufactured by Yokowaga.

TC/RTD Input Modules (Isolated Channels) receive signals from mV, thermocouple (TC), RTD, and potentiometer (POT), and they are isolated between the field and the system as well as in between each channel. They can be used in dual-redundant configuration.
