GE Fanuc IC660TBA026M Genius I/O 6 Channel 4-20mA Analog Output Block

GE Fanuc IC660TBA026M is a Genius I/O analog output block for GE Series 90 PLC system, equipped with 6 independent 4-20mA current source output channels. It receives digital control commands from Genius bus and converts into standard analog current signals to control valves, actuators and other field analog instruments.

This module has 0.15% high precision at 25℃, supports hold-last-state function when power supply fluctuates, and comes with channel overrange / underrange diagnostic. It adopts Genius dual bus communication, widely used as spare parts for power plant, chemical and oil & gas distributed control and PLC cabinet maintenance.
