Allen-Bradley BX640A1 is a BX Series industrial AC relay with a 120 V AC coil and a 10-contact configuration comprising six normally open and four normally closed contacts for multi-pole switching in control panels. The unit is designed for DIN-rail mounting, aligning with standard industrial control installations, and carries the 700-BX640A1 identifier as the model number. This configuration supports wiring schemes that require separate normally open and normally closed circuits in a single relay assembly, enabling compact, centralized control of complex machines.
