Specific wiring: Circuit designation Description Power supply VCC Positive power GND Negative power or Negative signal Output TH Positive temperature signal Positive humidity signal HR Note: The device does not provide a default communication line; the line color is for reference only. Common problems and solutions: When there is no output or an output error, the possible reasons are: 1. The corresponding error in the range leads to an error in the PLC calculation. For the range, refer to the technical specifications in Part 1. 2. The wiring method or the wiring sequence is incorrect. 3. The supply voltage is incorrect. 4. The distance between the transmitter and collector is too long, causing signal distortion. 5. The PLC's acquisition port is damaged. 6. The equipment is damaged. Weight: 178g / 6.28oz (approx.)
