Allen-Bradley 0D156 Relay

Allen-Bradley 0D156 Relay coil is a 230-250 VDC control coil designed to energize the corresponding Allen-Bradley relay or contactor in industrial control circuits. This coil accepts a DC control signal within the 230-250 V range and is used to operate the switchgear by pulling in the relay contacts when energized. The designation 0D156 places it among the legacy Allen-Bradley coil families associated with Bulletin 156 contactors, and it is commonly cross-listed with the 77D156 coil (230-250 VDC) in supplier catalogs. Typical applications include machine automation, process control, and safety interlock schemes where a DC control voltage is used to drive a relay or contactor coil. This part is sourced from Allen-Bradley (Rockwell Automation) and is listed as a replacement coil for relays requiring a 230-250 VDC coil, enabling straightforward substitution in compatible assemblies without altering control circuits.
