Allen-Bradley 700-HA33Z24-3-4 Industrial Relay

Allen-Bradley 700-HA33Z24-3-4 is a General Purpose Tube Base Relay from the 700-HA family, configured with a 24V DC coil and three pole double throw (3PDT) contacts, rated for up to 10 A of switching current. The device is designed for panel and machine control applications where reliable, multi-contact sequencing is needed, and it accepts Rockwell’s standard plug-in sockets that simplify replacement in field installations. Key features include a Push-To-Test control for quick energization checks, a Manual Override to operate the relay without applying control power, and a Pilot Light indicator that visibly shows when the relay coil is energized. Because it’s a general-purpose, tube-base relay with 3PDT contacts, it supports common control wiring and interlocking schemes in automation panels, signaling circuits, and logic switching where a compact form factor and straightforward serviceability matter. The 700-HA33Z24-3-4 is part of a broader ecosystem that includes compatible sockets and mounting accessories, enabling technicians to tailor the relay installation to a range of control architectures—from simple switch closures to multi-island logic networks.
