Allen-Bradley 700-C040A1 Control Relay 120 VAC Coil

Allen-Bradley 700-C040A1 is a control relay from the 700-series with a 120 VAC coil, designed to energize and switch control circuits in industrial automation equipment. It provides isolation between the controller logic and the power side, allowing low-voltage control signals to actuate higher-current loads through its internal contacts. When used in panel installations, this relay is typically paired with a matching Allen-Bradley socket or base in the 700 family, enabling plug-in installation and straightforward field replacement. The 700-C040A1 designation identifies a 120 VAC coil variant within the 700-series control-relay lineup, intended for systems that require a 120 VAC control coil.
