Bard 8301-081BX - C.PCOE Expansion PLC Board

Bard 8301-081BX is an OEM C.PCOE expansion PLC board, boxed for service replacement, used in select Bard wall mount and commercial HVAC control systems to expand controller I/O and support proper unit monitoring and sequencing. If your unit is showing control faults, missing inputs, or will not respond correctly to connected sensors and safety circuits, replacing the expansion board with the correct Bard part helps restore reliable communication and normal operation. Because control boards are model and revision specific, confirm your unit model and existing control platform before ordering so the 8301-081BX matches your factory configuration and connectors.

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.
