Carel PCOBAF0A21 Analog Input Controller Board

Carel PCOBAF0A21 Analog Input Controller Board is an eight‑channel analog input interface card designed for CAREL pCO programmable controllers, enabling direct connection of multiple sensor signals in HVAC and refrigeration systems. This CAREL board provides eight analog input channels and uses removable‑screw connectors for straightforward, field wiring, making it suitable for expanding sensing capability without replacing the main control unit. As part of CAREL’s pCO ecosystem, the PCOBAF0A21 integrates with compatible pCO boards and supports the standard analog input configurations used by CAREL controllers, feeding voltage or current signals into the control logic for monitoring variables such as temperatures and pressures. The module is built to withstand industrial environments and aligns with CAREL installation practices, allowing seamless incorporation into networked or multi‑board pCO setups when additional analog sensing points are required. Ideal for retrofit or new installations in air‑conditioning and commercial refrigeration projects, this model concentrates eight reliable analog inputs in a compact interface card, helping engineers scale existing CAREL control architectures without downtime or major redesign.
