ICS Triplex T8830 40 Channel Analog Input Terminal

ICS Triplex T8830 is a 40-channel analog input FTA (Field Terminal Assembly) for Trusted T8000 safety system, matched with T8431 series analog input module. It acts as the signal interface between field transmitters and TMR AI module, handling field analog signal wiring, overcurrent protection and signal distribution.

This FTA supports two-wire transmitter connection, each channel has independent fuse protection and LED power status indication. It adopts SmartSlot connector, supporting hot swap of the corresponding T8431 AI module without field wiring modification. It is widely used as spare parts for SIS cabinet maintenance in oil, gas and chemical industries.
