Allen-Bradley 700-CF310D Control Relay 120 VAC

Allen-Bradley 700-CF310D is a 4-pole IEC control relay (MCS-CF family) with a 110 VAC (50 Hz) / 120 VAC (60 Hz) AC coil. It provides three normally open (NO) contacts and one normally closed (NC) contact, suitable for multi-circuit switching and basic interlock logic in control panels. The relay uses screw terminals and offers mounting flexibility with either a dedicated base or DIN-rail compatibility, enabling clean, space-saving installations in industrial automation. This model is commonly used in PLC-driven control circuits to energize loads, isolate circuits, or implement safety-and sequencing logic in machine controls, where a four-pole device supports simultaneous control of multiple lines within a single relay package. It is cataloged as 700-CF310D and belongs to Allen-Bradley’s 700-CF IEC Control Relay line, designed for rugged industrial environments.
