Mitsubishi Electric SRD-80 DC Contactor Relay

The Mitsubishi Electric SRD-80 DC Contactor Relay is a DC-coil control device used to switch electrical loads in control circuits. It features a 120–125 V DC coil, allowing it to be driven directly from standard DC control signals found in panels and automation equipment. As a contactor, the SRD-80 provides the essential interface between low-voltage control circuitry and higher-current power circuits, delivering isolation and reliable switching when the coil is energized. This model sits in Mitsubishi Electric’s DC-contactor family and is built for industrial environments where a compact, dependable switching element is needed to control loads via a DC control input. Energizing the coil causes the contacts to close, completing the load circuit, while de-energizing opens the contacts for safe, controlled disconnection. The 120–125 V DC coil specification simplifies integration with common DC control systems, minimizing the need for additional voltage conversion in many installations. Suitable for inclusion in electrical control panels, test benches, and automation assemblies where a DC-coil contactor is appropriate.
