Binary Outputs
Analog Outputs
•AO1;
– Spare output.
– Voltage output is 0 to 10 Vdc, 500  minimum impedance.
– Current output is 4-20 mA, 500  max. impedance.
– Also can output 100 Hz PWM signal for control of a Trane fan-powered ECM fan setpoint
signal to the EC motor.
Note: ECM fan for future production.
• AO2;
–Spare.
– Voltage output is 0 to 10 Vdc, 500  minimum impedance.
– Current output is 4-20 mA, 500  maximum impedance.
– Also used on Trane VAV units for SCR electric heat 0-to-10 Vdc modulation control.
Note: For more information on wiring spare points, refer to the Tracer UC400 Programmable
Controller Installation, Operation, and Maintenance Manual (BAS-SVX20).
