Allen-Bradley 700-CFB400DJ Control Relay

Allen-Bradley 700-CFB400DJ is a MCS-CF control relay with a 24 VDC coil and four Form A (normally open) contacts, delivering four independent switching paths in a compact, plug-in package. Rated to handle up to 10 A on the load side, it is well suited for control circuits in industrial automation, including relay interlocks, sequencing logic, and PLC-driven control signals. The DJ suffix denotes an integrated diode across the coil to suppress voltage spikes, helping protect DC control electronics and improve reliability in energized/de-energized cycles. This 700-CF family device pairs with standard Allen-Bradley bases and sockets to simplify panel wiring and replacement in existing control architectures. Typical applications include automation panels, machine control relays, signal amplification in logic circuits, and automation sequencing where four separate normally open paths are required from a single compact relay. The unit adheres to the familiar 700-CF form factor used across Rockwell Automation's control-relay line, ensuring compatible mounting, electrical characteristics, and a consistent maintenance footprint across related components.
