Square D 8865 RMB-4 Relay Module

Square D 8865 RMB-4 Relay Module is a modular relay component in the Square D 8865 family designed for use in compatible Square D control panel assemblies. The RMB-4 variant adds relay outputs that interface with PLCs or control logic to switch field loads in industrial automation. As a Schneider Electric/Square D product, it follows the 8865 platform's mounting and electrical interface conventions to support straightforward installation and maintenance within legacy control systems. The RMB-4 designation identifies the RMB module within the 8865 line, making it suitable for expanding control logic within existing Square D panels without replacing primary hardware. Typical applications include automation panels in manufacturing, process control, and machine control where the 8865 ecosystem is already in use; for exact electrical specifications, coil voltage, contact configuration, current ratings, and mounting dimensions, consult the official Square D 8865 RMB-4 datasheet or a current Schneider Electric catalog entry.
