Wiring Inputs and Outputs
Wiring 0–20 mA Analog Inputs
Connect any 0–20 mA analog input to sensors such as humidity sensors and pressure sensors.
1.
Connect the shield to a common terminal at the terminal board and tape it back at the input
device.
Note:
Do Not use the shield as the common connection. For 3-wire applications, use a 3-
conductor cable with shield and for 2-wire applications, use a 2-conductor cable with
separate shield.
2. Connect the signal wire to an available input terminal.
3. Connect the supply wire to a 24 VDC or 24 VAC terminal as required.
4. Use the Tracer TU service tool to configure the analog input that references the corresponding
hardware termination.
