113247 - Miller 12VDC DPDT Enclosed Relay 20A 8-Pin Flange Mount

Reliable Control Switching with the Miller 113247 Relay

The Miller 113247 is a high-quality, enclosed relay designed to meet the rigorous demands of industrial welding equipment. As a genuine OEM component, this relay is engineered to precise specifications, ensuring seamless integration into compatible Miller power sources and wire feeders. Relays are critical components in the control logic of welding machines, often responsible for switching gas solenoids, wire feed motors, or contactor coils. The 113247 features a 12VDC coil, a common control voltage in modern welding circuitry, ensuring compatibility with standard logic boards and control transformers.

This specific unit utilizes a Double Pole Double Throw (DPDT) contact configuration. This versatile arrangement allows the relay to control two separate circuits simultaneously, offering both normally open (NO) and normally closed (NC) options for each pole. With a robust contact rating of 20 Amps at 120 Volts AC, this relay is capable of handling significant electrical loads without overheating or premature failure. This makes it suitable for switching auxiliary power circuits or controlling heavier inductive loads within the machine's internal architecture.

Durability is paramount in welding environments, and the Miller 113247 addresses this with its enclosed housing. The enclosure protects the sensitive internal contacts and mechanical armature from dust, metal shavings, and other airborne contaminants that are prevalent in fabrication shops. Furthermore, the relay is designed with a flange mount. This mounting style allows the component to be securely bolted to the machine's chassis or control panel, providing superior resistance to vibration compared to socket-only relays. This is essential for portable welding generators or shop machines that may be moved frequently. The 8-pin terminal layout provides standard connection points for secure wiring, ensuring reliable electrical conductivity and ease of installation for maintenance personnel.

When maintaining high-performance welding equipment, using genuine Miller parts like the 113247 relay is crucial for safety and longevity. Generic substitutes may not match the coil resistance, pull-in voltage, or contact material quality required by the original design, potentially leading to intermittent faults or damage to the control board. Trust in the OEM specification to keep your operations running smoothly.
