Schneider Electric 8501KPD12V51 Plug-In GP Relay

Schneider Electric's Square D 8501KPD12V51 Plug-In GP Relay is an eight‑pin plug‑in, DPDT general‑purpose relay with a 12 VDC coil. It delivers two normally open and two normally closed contacts, enabling two circuits to switch independently or a single circuit with a changeover contact in control panels and automation gear. As part of the 8501 KP family, this tubular plug‑in relay is designed for use with Schneider Electric plug‑in sockets, offering a modular, field‑replaceable control element for industrial electronics. The compact form factor makes it suitable for panel enclosures and control cabinets, while the 12 V DC coil simplifies interfacing with low‑voltage control circuits and PLC outputs. Typical applications include machine‑control sequencing, interlocks, and logic circuits in manufacturing automation, HVAC controls, and process equipment where reliable relay operation is required. For exact electrical ratings per contact, coil current, and peak surge characteristics, consult the official 8501KPD12V51 datasheet from Schneider Electric to verify compatibility with your loads and supply conditions.
