Allen-Bradley 700-P400A1 Electromechanical Relay

Allen-Bradley 700-P400A1 is a Bulletin 700-P electromechanical industrial control relay designed for rugged automation tasks. It represents a four-contact variant within the 700-P family, built to switch load circuits in industrial equipment with a compact form suitable for panel mounting. The model is cataloged as 700-P400A1 and is listed in sources as a 600V class industrial relay, making it appropriate for mid-range control applications in machines, conveyors, and process equipment. As part of the 700-P family, it supports optional timing and latch accessories that tailor operation for sequencing, interlocking, and timing-based control logic; 700-P400A1 is compatible with these accessories per the documented product data. The exact coil voltage and precise contact arrangement are defined by the catalog data for this model, so the official Rockwell Automation documentation should be consulted to confirm the specific electrical specifications for your installation. This relay embodies the reliability typical of Allen-Bradley electromechanical relays, serving as a durable, remote-switching element in control panels and machinery where robust mechanical switching is required.
