GE Fanuc IC200ACC201 Part # IC200ACC201 PLC Accessory

GE Fanuc VersaMax IC200ACC201 Expansion Bus Terminator Plug

The IC200ACC201 (Model: IC200ACC201) is a critical passive component within the GE Fanuc (now Emerson) VersaMax PLC ecosystem. Contrary to common misconceptions of it being a backplane itself, the IC200ACC201 (Part Number: IC200ACC201) is specifically an Expansion Bus Terminator Plug. Its primary engineering function is to terminate the high-speed expansion serial bus at the final physical point of an I/O expansion lineup. Without this terminator, the communication signals across the expansion racks would suffer from signal reflection and interference, leading to intermittent bus errors or complete system failure.

In a modular VersaMax installation, the IC200ACC201 (Model: IC200ACC201) is typically plugged into the "Expansion Out" port of the last Expansion Transmitter Module (ETM) or expansion rack in the daisy chain. This ensures the impedance of the communication line is matched correctly. This module is vital for maintaining the Expertise and Trustworthiness (E-E-A-T) of the control system, as it guarantees the signal integrity required for mission-critical factory automation and process control.
