Allen-Bradley 700-CF220D Control Relay

The Allen-Bradley 700-CF220D is an IEC-style MCS-CF control relay with a four-pole contact arrangement: two normally open and two normally closed contacts, designed to switch control logic in industrial equipment. This 110 VAC coil variant is wired through screw terminals and supports base or DIN-rail mounting for flexible panel installation. As part of the 700-CF family, it provides compact, rugged isolation between control circuits and larger power circuits, making it suitable for sequencing, interlock tasks, and signaling in automation systems. Key specifications include four poles (2 N.O., 2 N.C.), 110 VAC coil, and mounting options via screw terminals with base or DIN-rail compatibility. Typical applications include motor-control and starter circuits, conveyors, presses, and other machinery where a multi-pole control relay conditions control signals before energizing contactors or safety relays. The 700-CF220D variant is commonly used in IEC-based control panels and is compatible with standard control-relay practices in Allen-Bradley installations, offering dependable operation in environments requiring reliable logic isolation and straightforward wiring.
