Wiring Analog Outputs (AOx)

Analog outputs can be configured to provide either a discrete signal of 0 or 12 VDC or a linear signal ranging from 0 to 10 VDC. The discrete signal can

be used to generate a pulse wave modulation (PWM) signal or a simple two-state signal.

Analog output connectors accept wires between 0.75 mm² (18 AWG) and 1.5 mm² (16 AWG).

If an analog actuator is being controlled, connect the 0 to 10 VDC output, along with an external 24 VAC power source, to the analog actuator according

to the following figure.

The onboard 24 VAC power supply can be used to power 0-10 V actuators according to the following figure (ECB-PTU-208 and ECB-PTU-308 only).
