Specific Wiring: Circuit Identification Description Power Supply Positive Power GND Negative Power or Negative Signal Output Positive Temperature Signal RH Positive Humidity Signal Note: The device does not provide a communication line by default, The line color is for reference only. Common Problems and Solutions: When there is no output error, the possible reasons are: 1. The corresponding error in the range leads to an error in the PLC calculation. For the range, please refer to the technical specifications in Part 1. 2. The wiring method is incorrect or the wiring sequence is incorrect. 3. The supply voltage is incorrect. 4. The distance between the transmitter and the collector is too long, causing signal disturbance. 5. The PLC acquisition port is damaged. 6. The equipment is damaged. Weight: 178 g / 6.28 oz (approx.) How to Use: Installation Method: 1. Wall Mounting: The back of the transmitter is equipped with a slide rail mounting plate. First, remove the mounting plate. There are two wall plugs and two self-tapping screws in the accessories. First, drill two holes with a diameter of 5 mm and a depth of ≥30 mm on the wall (hole spacing is 70 mm). After inserting the wall candle, secure the slide rail mounting plate to the wall with self-tapping screws and then slide it into the transmitter. 2. The transmitter slides directly into a standard 35 mm rail. Package list: 2 x screws, 2 x wall candles, 1 x temperature sensor, 1 x user manual
