Bard 8201-159BX - DPDT pilot duty relay, 24V coil
The Bard 8201-159BX is an OEM DPDT pilot duty relay with a 24V coil used in Bard wall-mounted HVAC equipment to switch control circuits reliably from a low-voltage signal. This relay is commonly applied where the unit needs one control input to operate multiple circuits, such as staging functions, fan and compressor control logic, or other interlocks depending on the specific model and wiring diagram. Replacing a weak or intermittent relay with the correct Bard part helps restore consistent call-for-operation response and prevents nuisance shutdowns caused by contact wear or coil issues. Confirm DPDT contact form, coil voltage, and terminal layout against your unit schematic before ordering to ensure proper fit and function.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
