BRD04877
The Trane BRD04875 Dual Analog I/O Board provides two configurable analog inputs/outputs (e.g., 4–20 mA or 0–10 V) for connecting sensors or external devices, enabling precise control in Trane chillers and HVAC systems.
The Trane BRD04877 Relay/Starter Board is a factory-engineered OEM control module featuring quad relay outputs, enabling control of multiple high-power circuits—such as compressors, fans, pumps, or starters—using low-voltage signals from the system controller.
Equipped with pluggable terminal blocks and built on a robust green PCB with stainless-steel connectors, it ensures durability in harsh industrial environments. Ideal for use with Trane and American Standard chillers (RTAC, RTWD series), the board is programmable or “bound” to the unit’s controller (e.g., Tracer CH530 via TechView) before operation.
This board supersedes older parts such as BRD‑4877, BRD‑3542, MOD2763, offering full OEM compatibility and a guaranteed fit
