ACTION PAK 4051-2167U Solid State Relay Plug-In

ACTION 4051-2167U Action Pak Solid State Relay Plug-In is a compact plug-in module that provides solid-state switching within an Action Pak base used in Rockwell Automation control systems. The unit is specified for 120V-AC operation and carries a 4-20mA signaling characteristic, aligning with common industrial control interfaces for sensing and control loops. As a solid-state relay, it has no moving parts in its switching path, which minimizes wear and enables quiet operation in automation panels. The 4051-2167U is designed to drop into compatible AB Action Pak bases to control AC loads in equipment such as automated conveyors, packaging systems, and machine tools where space is at a premium and fast switching is beneficial in a compact package. Because it is a plug-in module, replacement and servicing can be performed with minimal wiring disruption, provided the base hardware and electrical ratings match the part number. For installation specifics, base compatibility, and any additional electrical ratings beyond voltage and signaling, consult Rockwell Automation's official literature and the product's documentation to ensure proper fit within your control architecture.
