Allen-Bradley 700DC-F400 DC Servo Drive Controller

The Allen-Bradley 700DC-F400 is a legacy DC control relay/contactor from Rockwell Automation’s 700DC family, used to switch DC power in industrial control panels and automation circuits. Variants in this line carry suffix codes such as Z24 (24 VDC coil) and ZP, which denote coil voltage and configuration options, and you may see references to 700DC-F400-Z24 or 700DC-F400-ZP in distributor listings. This device is intended for DC switching applications in industrial equipment, often employed to energize or de-energize DC motors, solenoids, or control circuits under PLC or relay logic control. Availability today is typically through third-party distributors or surplus channels as a legacy component, with exact specifications (coil voltage, contact arrangement, and current rating) determined by the exact sub-model and by the unit’s data plate; verify the suffix and datasheet for the precise electrical ratings before application. When retrofitting or sourcing replacements, ensure compatibility with your system’s control voltage and the intended load, and consult Rockwell’s product literature or authorized distributors to confirm current data and cross-compatibility with other Allen-Bradley contactor products.
