The PCM984230 executes control logic inside Schneider’s Modicon 984 automation platform. This CPU controller measures roughly 12.0 inches long, 1.4 inches wide, and 6.5 inches high. Moreover, it weighs about 1.8 pounds, which suits standard rack installation. Engineers specify the PCM984230 when they need dependable processing for legacy 984 control systems.
Technical Specifications and Interface Details
The module runs ladder logic programs and therefore manages discrete and register-based control tasks. Specifically, it carries onboard memory for application code and process data. Additionally, rear connectors link the unit to the Modicon 984 backplane and I/O modules. Front-panel indicators reveal run, fault, and battery status at a glance.

Energy Storage and Program Retention
A backup battery on the PCM984230 preserves application code during power interruptions. Consequently, the CPU resumes operation without reloading programs from external media. Internal capacitors further stabilize logic voltage across brief supply dips. This buffering therefore protects critical control sequences in continuous production environments.
Installation and Compatibility Notes
Because the PCM984230 slides directly into Modicon 984 racks, technicians complete installation quickly. They should confirm connector alignment before they apply power to the system. Furthermore, the module integrates smoothly with existing 984 control hardware. Always store spare units in anti-static packaging to protect sensitive circuitry.
