261010 - Miller 261010 Enclosed Relay 24VDC DPST 30A

Technical Overview of the Miller 261010 Relay

The Miller 261010 is a specialized enclosed relay designed for integration into Miller welding power sources and auxiliary equipment. As a critical component in the electrical control system, this relay manages the switching of high-current circuits based on low-voltage control signals. It features a 24VDC coil, a standard voltage for internal control logic in many industrial welding machines, ensuring seamless compatibility with existing control boards and wiring harnesses.

Structurally, the device is built with a Double Pole Single Throw (DPST) configuration. This allows it to simultaneously control two separate circuits or lines while being actuated by a single signal, a common requirement for isolating power or engaging multiple subsystems at once. The contacts are rated for 30 Amps at 24VAC, providing substantial power handling capabilities necessary for the demanding loads often found in welding environments, such as fan motors, solenoids, or secondary power stages.

Installation is facilitated by a flange mounting design, which allows the relay to be securely bolted to the machine chassis or electrical panel, preventing movement due to vibration—a common stressor in industrial settings. The unit connects via a 4-pin interface, ensuring a positive and correct electrical connection. The enclosed housing serves to protect the mechanical contacts from environmental contaminants like metal dust and grime, extending the service life of the component and maintaining reliable operation over time.
