• C.Pcoe Expan. PLC Board-Boxed

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.
