Trane BRD04873 Dual Binary Input Board
The Trane BRD04873 is a dual high-voltage binary input board fitted in the control panels of Trane chillers running Tracer CH530 or TD7 controls. It reads two high-voltage digital inputs, interlocks, permissives, external switch positions, and reports their state to the chiller controller. When it fails, the controller stops seeing a signal it depends on, and the machine either refuses to start or locks out on a fault with no mechanical cause behind it.
Two things before you order. This is an input board, not the main chiller controller, if your CH530 or TD7 module itself has failed, this isn’t the part. And Trane specifies that this board requires programming; it is not a drop-in.
Cool.sa supplies BRD04873 as a genuine Trane OEM part, held in stock inside Saudi Arabia alongside our full range of chiller spare parts, with a VAT invoice and delivery to project sites across the Kingdom.
Key Features
- Dual high-voltage binary input, two digital channels reported to the chiller controller
- Pluggable connectors: field wiring transfers without cutting or re-terminating
- Genuine Trane OEM, original specification and part marking
- Covers Trane scroll, screw and centrifugal platforms on CH530/TD7 controls
- Single current part replacing six legacy numbers
- Small and light, so urgent air freight costs almost nothing
Benefits of Using This Product
A failed input board causes one of the most frustrating faults in chiller service: nothing is mechanically wrong, but the machine won’t run. Compressors are healthy, charge is fine, and the controller is locking out on a permissive it can no longer read. Teams lose days to it.
Replacing the board restores the input path and fixes the actual cause. Using the genuine OEM component means the board reports exactly what the controller expects, no signal mismatch, no intermittent behaviour returning three weeks later at peak load.

Frequently Asked Questions
Q1. Is this a genuine Trane part?
Yes. Genuine Trane OEM in original packaging with original part marking. We don’t sell aftermarket copies of this board. Source documentation available on request.
Q2. Does it need programming after installation?
Yes. Trane’s specification states programming is required. The board must be configured to your unit with the service tool before the chiller operates correctly. A board that seems unresponsive after fitting is usually unconfigured, not faulty.
Q3. My old board says BRD04279 / MOD02761 / MOD00099. Is this the replacement?
Yes. BRD04873 supersedes all of them. Send a photo for written confirmation.
Q4. Is this the main chiller control board?
No. It’s a dual binary input board feeding two digital inputs to the controller. The CH530 or TD7 main module is a separate part.
Q5. Which chillers use it?
Units on CH530 or TD7 controls: CGAM, CXAM, CVGF, CVHG, RTAC, RTAF, RTHD, RTWD, RTUD. Unit specific, so confirm against model and serial.
Q6. How do I know it’s the board and not the field device?
Check the device, wiring, connector seating and board supply voltage first. If the device operates correctly but the controller never sees the change, the input board is the likely cause.
