The wiring of the transmitter depends on the model and output type. The instruction manual provides wiring diagrams for different scenarios. Here are the general guidelines:
- For models with 4-20 mA RH output, with or without 4-20 mA temperature output: Wire the transmitter according to Figure 3 in the manual. The RH channel should always be powered, and if the temperature channel is not used, it can be left disconnected.
- For models with 4-20 mA RH output and a passive thermistor temperature sensor: Wire the transmitter according to Figure 4 in the manual. The RH output wiring is the same as the previous model, and the passive thermistor temperature sensor wires to terminals 3 and 4.
- For models with 0-5 V or 0-10 V RH output, with or without 0-5 V or 0-10 V temperature output: Wire the transmitter according to Figure 5 in the manual. Pay attention to the polarity when using DC power. Both RH and temperature outputs can be used simultaneously, and the maximum load is 5 mA.
- For models with 0-5 V or 0-10 V RH output and a passive thermistor temperature sensor: Wire the transmitter according to Figure 6 in the manual. The RH output wiring is the same as the previous model, and the passive thermistor temperature sensor wires to terminals 4 and 5.
Please refer to the specific wiring diagrams in the manual for a visual representation of the connections.
Note: It is important to follow national and local electrical codes and use copper conductors only.
