Carel PCO3 pco3000as0 Programmable Controller

The CAREL pCO3 PCO3000AS0 is the small, programmable electronic controller in CAREL’s pCO3 family, designed for HVAC and refrigeration applications and built to manage sensors, actuators, and control logic in a compact package. The AS0 variant is the “Small” version (without a built‑in terminal) and includes 4 MB of flash memory for firmware and user programs, all housed in CAREL’s plastic case. This unit is documented as Rev. 2.011, a revision commonly listed on distributor and reseller pages. Like other pCO3 controllers, it supports CAREL programming tools and networking options, including USB‑485 adapters (CVSTDUTLF0) and the WINLOAD32 utility, enabling integration with pLAN networks and other CAREL devices for HVAC/R control tasks such as temperature regulation, valve and fan control, and safety interlocks.
