Schneider Electric 8897EQ5110 MCP21 CPU Module

Schneider Electric's Square D SYMAX MCP21 CPU Module, part number 8897EQ5110, Series B, is a central processing unit card for the SYMAX PLC family. It is designed to plug into a SYMAX CPU rack and provides the processing core for executing control programs and coordinating communications among SYMAX modules in a complete control system. As a CPU module, the MCP21 handles the execution of ladder-like logic and manages data exchange with SYMAX I/O racks and peripherals in legacy automation setups. The Series B designation identifies a specific revision of the MCP21 family. Typical applications include process control, packaging lines, material handling, and general machine automation that rely on Square D SY/MAX hardware. When used with compatible SYMAX I/O racks and network interfaces, this CPU module supports the established Square D SYMAX control architecture and programming workflows common in older installations. Buyers often select the MCP21 CPU Module to extend legacy SYMAX systems or to source a replacement for in-service equipment with minimal changes to a running control network.
