About the PMC-512A

PMC-512-A is CET’s latest offer for the economical multi-circuit monitoring of Data Centers, Telecom Base Stations, Industrial & Commercial Buildings. Housed in a compact DIN Rail Mount enclosure, the PMC-512-A is perfectly suited for high-density metering applications. The PMC-512-A features quality construction with multifunction and high-accuracy measurements with an optional color touch-screen HMI that supports up to 16 devices simultaneously over a RS-485 network. The PMC-512-A comes standard with 12xDIs for status monitoring, 1xDO for control or alarming as well as 1xAI for temperature measurement or other analogue input applications. The standard SOE Log records all setup changes, alarms and DI/DO operations in 1ms resolution. With dual RS-485 as standard feature supporting Modbus RTU, the PMC-512-A can easily be deployed in a stand-alone system with its Touch Screen HMI or simultaneously with a centralized monitoring and control system for an AC power distribution network.
