Schneider Electric PC-A984-130 CPU Module

The Schneider Electric Modicon PC-A984-130 CPU module is the central processing unit for 984-series Compact PLCs, designed for 24 VDC operation and intended to be installed in compatible Modicon hardware to execute ladder logic and manage I/O. It incorporates an 8 MHz CPU with 2K of state RAM and 1.5K words of user memory, and it uses a lithium battery-backed memory protection scheme to preserve critical data across power cycles. This CPU module is part of the Modicon 984 family, a legacy line known for compact, field-installable control. Schneider Electric also offers an official upgrade path from PC-A984-130 to newer M340 controllers for customers seeking modernization of legacy installations. The PC-A984-130’s compact form factor and 24 VDC input compatibility make it well-suited for retrofit projects or greenfield builds requiring proven, industrial-grade PLC performance in a compact footprint.
