Allen-Bradley 700-P400A1 Convertible Contact AC Control Relay

Allen-Bradley 700-P400A1 Convertible Contact AC Control Relay is a four‑NO, open‑type control relay cartridge in the 700‑P family, designed for direct‑drive control in industrial panels with DIN‑rail mounting. It uses an AC coil rated for 110 V at 50 Hz or 115–120 V at 60 Hz, and provides four normally open contacts with a 10 A AC current rating, switching up to 600 V AC. The 700‑P400A1 is a convertible contact cartridge, enabling field configuration within the 700‑P lineup without replacing the entire relay assembly. This open‑type relay is designed for DIN‑rail mounting in control panels, making it suitable for machine controls, automation logic, interlocks, and other industrial control applications. Coil voltage, frequency, contact arrangement, and ratings align with common North American industrial standards for control relays.
