Allen-Bradley 700DC-PK400Z24 DC Control Relay is a four-pole, 24 VDC coil industrial relay from Rockwell Automation’s 700-P/700DC-P family. This open-type device provides four normally open contacts and is designed for rail-mount installation in control panels, making it well-suited for DC control circuits in automation systems. The PK400Z24 variant sits within the 700DC-P line and shares the 24 VDC coil with four NO contacts, enabling reliable switching of control signals driven by PLCs or other control circuitry. Typical applications include signaling, interlock and control tasks in industrial equipment, conveyors, and machine automation where a discrete DC switch is required.
