Allen-Bradley 700-HA33A24 3PDT 24V Coil Relay

Allen-Bradley 700-HA33A24 is a general‑purpose tube‑base relay with a 24 VAC coil and three Form C contacts (3PDT). Rated for up to 10 A, it enables three independent NO/NC circuits from a single coil, suitable for compact control panels and PLC‑based circuits. The coil operates at 24 V AC with a 50/60 Hz input, and the unit features Push‑To‑Test and a Manual Override for maintenance checks. This -3 variant does not include an integrated pilot light (the -3-4 variant adds a pilot lamp). Use cases include interlocking and sequencing of solenoids, valves, and small actuators in machine controls, conveyors, and packaging lines, where a single 24 VAC coil can drive multiple loads. The relay is designed for use with Allen-Bradley tube-base sockets and is part of the 700 family of general-purpose relays commonly used in industrial automation.
