PCO3000EM0 -PCO3 Medium version, 4 MB Flash memory + PGD1 BUILT-IN

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. Given the increasing demand for integration, pCO3 can interface with many of the most commonly-used serial communication standards, and, using optional cards, can be integrated into the most widespread BMS systems. pCO3 include connection to ratiometric pressure sensors; integration of pGD technology for the Built-In terminal; upgraded programming key; 3 serial ports: a serial one, pLAN and two optional, Field Bus and BMS, available with different communication protocols. All of these features ensure a level of excellence in responding to the needs of the HVAC/R market.
