pCO3 represents the most advanced offering by CAREL in the field of programmable controllers. pCO3 is designed for many air-conditioning and refrigeration applications. It comes in various sizes, according to the I/O and power requirements (Small, Medium, Large, Extra Large). All the boards feature a 32-byte microprocessor, and consequently the calculation power and operation processing speed have been significantly increased. As for all the pCO series controllers, pCO3 comes in a plastic case that ensures a high index of protection and reduces the risk of electrostatic discharges due to incorrect handling. In addition, assembly is simplified by the DIN rail mounting system, allowing significant saving in wiring and assembly times.
