24 Vac ±10%, 50–60 Hz
14 VA power consumption
26 Vdc (25 V min, 28.8 V max)
Single Class 2 source only, 100 VA or less
Belimo brushless DC motor, torque 45 inch-pounds (5 Nm), runtime 154 seconds
To connect the actuator cable and the VAV Zone II
For communication with the controller network using BACnet ARC156 (156 kbps)
or BACnet MS/TP (9600 bps – 76.8 kbps)

Supports up to 5 wireless and/or ZS sensors, and one Equipment Touch or
TruVu™ ET Display.

Supplies 12 Vdc/200 mA power to the Rnet at an ambient temperature of
77°F (25°C) with a 24 Vac nominal power source.
NOTE Ambient temperature and power source fluctuations may reduce the
power supplied by the Rnet port.
NOTE If the total power required by the sensors on the Rnet exceeds the power
supplied by the Rnet port, use an external power source. The Wireless Adapter,
Equipment Touch, or TruVu™ ET Display must be powered by an external power
source. See the specifications in each device's Installation and Start-up Guide to
determine the power required.
For system start-up and troubleshooting
Accepts Precon type II thermistors (10kOhm at 77°F [25°C])
Range: -50°F (-45.5°C) to 250°F (121.1°C)
A 3.3 Vdc wetting voltage used to detect the contact position, resulting in a 0.3
mA maximum sense current when the contacts are closed.
0-5 Vdc. Input impedance is approximately 30 kOhms
10 bit A/D
#OPN-VAVB1-02: 1 binary output
#OPN-VAVB3-02: 3 binary outputs

Relay contact rated at 1 A max. @ 24 Vac/Vdc. Configured normally open.
1 analog output, 0–10 Vdc (5 mA max). The controlled device must have a
minimum of 2000 Ohms resistance measured from its input to ground and must
share the same ground as the controller.
