Multi-channel isolated thermocouple acquisition with power, communication and input isolation. Each channel is galvanically isolated from one another, with an isolation voltage of 400 V. It adopts multi-AD parallel acquisition and refreshes all channels within 2 seconds. Each channel input is equipped with overvoltage protection.Supports LED indicator and wide-temperature LCD with Chinese/English menu display. A default 60-minute automatic screen-off function reduces power consumption. Built-in keys facilitate on-site commissioning and configuration.Equipped with two independent isolated lightning-protected RS485 ports, supporting standard MODBUS-RTU communication protocol. Wide DC power supply range of 10–30 V. Integrated rectifier bridge design enables normal operation even under reverse power connection.
