BASIC INFO
Yokogawa TC/mV Input Module AAT145-S00
STANDARD SPECIFICATIONS of AAT145-S00
TC/RTD Input Modules (Isolated Channels)
AAT145, AAR145 These modules 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.
