Allen-Bradley 700-HA33Z24 Relay

Allen-Bradley 700-HA33Z24 Relay is a general-purpose, tube-base relay with a 24 V DC coil and three Form C (3PDT) contacts, rated for 10 A. It is designed for plug-in installation and is paired with the 700-HN203 socket for panel mounting and quick replacement in control circuits. The three independent Form C contacts allow switching of up to three circuits from a single coil, enabling compact control of solenoids, signaling devices, or small loads in automation systems. This model is part of Allen-Bradley’s 700 family, commonly used in industrial control, automation panels, and PLC-related output tasks, where 24 V DC coils and 10 A per contact are suitable. Variants exist that add features such as a built-in pilot light (e.g., 700-HA33Z24-4) or different packaging configurations, but the core 700-HA33Z24 delivers a 24 V DC coil, 10 A contact rating, and 3PDT contacts in a tube-base form factor with socket 700-HN203.
