Allen-Bradley 700-CF400 General Purpose Control Relay

Allen-Bradley 700-CF400 General Purpose Control Relay is a four-pole, four normally open (4 NO) control relay designed for general purpose switching in industrial panels. This Bulletin 700-CF family device is rated for up to 25 A and is commonly used to switch control circuits in three-phase systems, motor control, and interlock logic within automation panels. The 700-CF400 is available in multiple coil voltages via suffix variants—for example EJ denotes a 24 V DC coil, D a 110 V AC coil, and VA a 230 V AC coil—with other suffixes offering additional voltages to fit your control supply. Some CF400 variants in the family specify coil ratings such as 240 V 50 Hz / 277 V 60 Hz on related models, while the standard units feature AC-rated coils and screw-terminal wiring for dependable connections. Mounting options include base or DIN-rail configurations, and the unit uses screw terminals for secure wiring in compact panel layouts. In practice, the 700-CF400 serves as a robust, replaceable solution for general-purpose control tasks in automation systems, providing reliable switching for loads governed by PLCs or other logic devices without resorting to solid-state devices.
