1.Temperature sensingThere are on the deviceDC12V、RS485① , switch input, temperature sensor, with4individualInterface.
2. DC12V connection12VPower supply (pay attention to the positive and negative poles of the power supply).
3. RS485①Connect the RS485 terminal of the monitoring host(Note:When connecting the RS485 bus, pay attention to the polarity of the two wires. It is required that 485+be connected to 485+/A and 485- be connected to 485-/B. Communication cannot be achieved if the wires are reversed.）.
4. The switch input can be connected to one switch.
5. The temperature sensor is connected to a high-temperature probe (note that it cannot be extended, as the wire has already been connected at the factory).
