GE Fanuc IC660BBA025N1 Analog Output Block

Core Performance & Industrial Application

The GE Fanuc IC660BBA025N1 is a 24/48VDC current-source analog output block from the Genius I/O system.

It provides six independent 4-20mA analog output circuits to drive field actuators, control valves and positioners over current loops.

Outputs 5 and 6 can additionally be used for voltage output applications, with software configuration and per-circuit fault reporting.

It features output hold-last-state or default setting, output feedback checking and advanced overrange / underrange diagnostics.

It supports CPU redundancy and connects to the Genius serial bus for distributed I/O in GE Series 90-30 / 90-70 PLC systems.

It is widely used as spare replacement in process control and manufacturing I/O racks.
