Allen-Bradley 700-HA32Z24-4 Industrial Control Relay

Allen-Bradley 700-HA32Z24-4 is a general‑purpose, plug‑in tube‑base relay from Rockwell Automation. It uses an 8‑pin tube‑base socket and provides DPDT (two Form C) contacts rated to switch up to 10 A with a 24 VDC coil. The -4 suffix denotes an LED/pilot‑light option for visible energization in compatible control panels. This compact relay is designed for panel‑mounted control circuits and is commonly used to drive solenoids, signaling indicators, interlocking circuits, and small motor loads in automation setups. The 700‑HA family is compatible with standard Allen‑Bradley 700‑H sockets, including 700‑HN100 and 700‑HN204, enabling straightforward replacement in existing installations. Documentation for 700‑HA32Z24‑4 confirms its configuration as a 2PDT/DPDT device with a 24 VDC coil and a 10 A switching capability. In practice it serves as a reliable control element in machine control logic, sequencing, and general control roles where isolation between control circuits and switched loads is required.
