The relay designated as Allen Bradley 700-CFB310D serves as an industrial control relay within the Bulletin 700 series. This unit operates efficiently between 110 to 120 Volts AC as the rated control supply voltage. It is compatible with frequencies ranging from 50 to 60 Hertz, making it applicable for various electrical systems.

In terms of configuration, this relay contains four poles, providing three Normally Open (NO) contacts along with one Normally Closed (NC) contact. Bifurcated gold-plated contacts enhance reliability and ensure optimal performance under demanding conditions. The relay also features an opening delay duration of 70 to 125 milliseconds when paired with an external diode.

For installation, users can mount the relay via a DIN rail or utilize screw mounting methods, providing convenient options for integration into control systems. The terminal type used in this relay comprises screw terminals for secure connections.

Electrical ratings include a peak impulse withstand voltage of 6 kilovolts, along with a dielectric withstand voltage rated at 2.5 kilovolts. The relay supports an impressive electrical life cycle of 1,500,000 operations, indicative of its durability and longevity. Resistance to external forces is also impressive, with shock capabilities rated at 30 G for a duration of 11 milliseconds. Furthermore, the relay can endure operational vibrations of up to 2 G and non-operational vibrations of up to 5 G.
