Carel p500bab000s0 Programmable Controller

Carel pCO5+ small programmable controller, P+500BAB000S0, rev. 2.220, is a compact unit in CAREL's pCO5+ family designed for HVAC/R and refrigeration equipment. This small-size variant includes a USB port for local programming and diagnostics, enabling configuration and service without external programming hardware. As part of CAREL's pCO5+ platform, it shares the same pin-to-pin footprint and software ecosystem as other pCO5+ controllers, facilitating upgrades and expansion within the family. The device is intended for climate-control applications in commercial and industrial cooling and heating systems where space on the panel is at a premium. Typical use cases include control of auxiliary fans, pumps, compressors, or valve actuators in packaged HVAC units and refrigeration equipment, with the USB interface supporting rapid setup and field adjustments. Named as the USB-enabled small-size variant, the P+500BAB000S0 aligns with CAREL’s USB-capable P+500B family for quick commissioning in field installations.
