Allen-Bradley 700-HA32Z12-4 GP Tube Base Relay

The Allen-Bradley 700-HA32Z12-4 GP Tube Base Relay is a general-purpose DPDT relay with a 12 V DC coil and a 10 A contact rating, designed for panel mounting in industrial control systems. This tube-base device provides two changeover contacts (DPDT) for signaling and interlocking tasks and includes a built-in pilot light on the -4 variant to indicate when the relay coil is energized, aiding quick diagnostics in control panels. The compact tube-base form factor accepts compatible Allen-Bradley 700-series tube sockets for easy plug-in replacement and wiring via PIN terminals. Typical applications include energizing solenoids, small indicators, and interlock circuits in equipment such as conveyors, presses, packaging lines, and machine tools, where reliable actuation and visible status indication are beneficial. As part of the 700-HA General Purpose Tube Base Relay family, it combines rugged mechanical construction with straightforward maintenance, making it suitable for retrofit projects in legacy automation setups while preserving familiar wiring schemes and diagnostics.
