Schneider Electric PC-E984-255 Logic CPU Module

Schneider Electric PC-E984-255 Logic CPU Module is a compact CPU for the Modicon 984 family, delivering 16K of user logic memory and 1 MB of external memory, powered from 24 V DC. This CPU module fits into Schneider’s 984 Compact PLC architecture to run ladder and structured logic for sequencing and control of I/O in small- to mid-size automation tasks. It offers Modbus communication for interfacing with field devices and other controllers, enabling straightforward integration on industrial networks. The module uses the 24 VDC power supply commonly used in factory automation and is designed to mount in the 984 Compact controller assembly alongside compatible I/O racks and expansion modules. Typical applications include machine control, packaging lines, conveyors, and basic process control where deterministic execution and reliable timing are essential. The PC-E984-255 represents a higher-memory option within the 984 family, providing a balance of memory capacity and compact form factor for rack-based control solutions.
