The main function of the WL-6800S computer room monitoring workstation is to collect environmental conditions such as temperature, humidity, smoke detectors, door magnets, and water immersion in the computer room. In addition, it can also detect the voltage, current, active power, reactive power, total energy, frequency, and other power supply status of the main and backup power supplies in the computer room. The communication protocol is MODBUS-RTU, and the upper computer can access real-time data of the device through Ethernet. The workstation is equipped with an embedded controller, which controls one RS-485 communication and can collect data from 8 temperature and humidity devices and 2 power devices.
