Wiring analog outputs
The Tracer MP581 controller has six analog outputs. These outputs can
be either 0–10 Vdc outputs or 0–20 mA outputs. Analog outputs control
actuators and secondary controllers.
To wire an analog output:
1. For three-wire applications, use a 3-conductor cable with a shield. For
two-wire applications, use a 2-conductor cable with a shield. Connect
the shield to a common terminal at the termination board and tape it
back at the output device (see Figure 35). Do not use the shield wire
as the common connection.
2. Connect the signal wire to an available analog output terminal
(AO1–AO6).
3. Connect the supply wire to a 24 Vac terminal as required.
4. Use the Rover service tool to configure the analog output.

NOTE: To reduce the potential for transients, locate output
devices in the same room with the Tracer MP581.
