It is applied to data acquisition of data center computer room, with DC output, AC output, switch value acquisition, switch output and data communication functions. If one RS-485 serial port can be set to communicate with upper computer, one RJ45 serial port can be used to read temperature and humidity. It can be equipped with fire interface, smoke detection interface, water leakage interface, background light power supply and built-in buzzer.
