BRD04879
The Trane BRD04879 is a brand-new OEM Quad Relay Output Board with a pluggable terminal connector. It provides reliable switching for up to four high-voltage circuits—compressors, pumps, fans—within Trane chillers and HVAC equipment.
The Trane BRD04879 Quad Relay Output Board is an OEM-grade module designed to manage up to four electromagnetic relay outputs, enabling independent control of high-voltage AC circuits. It’s commonly used in large-scale HVAC/R systems, including Trane’s RTWD, RTAC, and CGAM chillers—often paired with Tracer CH530 or TD7 controllers. The board features a green PCB, durable connector, and stainless-steel terminals designed for industrial durability. It replaces older modules such as BRD-4879, BRD-2948, BRD-02948 and is pre-programmed at the factory, requiring unit-specific binding before operation.
