The 700-CF220B industrial relay by Allen Bradley is engineered for versatile control applications. Designed to operate with AC voltage, this relay accommodates input requirements for both 50 Hz (440 V) and 60 Hz (480 V) frequencies. Users can mount this unit using DIN-rail or screw methods, providing flexible installation options. Auxiliary contacts are arranged on the side and comply with NEMA A600 and Q600 ratings, adding functionality to the base relay operation.

Constructed with durability in mind, the device features a rated impulse strength of 6 kV, ensuring it can withstand surges typically encountered in industrial settings. The relay utilizes screw terminals for secure connectivity, facilitating reliable power and signal connections. For applications requiring precise timing, the opening delay rating ranges from 70 to 125 milliseconds with the inclusion of an external diode, which aids in efficient control behavior.

This unit is suitable for high-altitude applications, supporting installations up to 2000 meters without derating. Operational ambient temperatures extend from -55 to 80 °C, enabling the relay to function effectively across a broad range of environmental conditions.
