Specifications
Driver
drv_vvtopn02
Power
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
Actuator
Belimo brushless DC motor, torque 45 inch-pounds (5 Nm), runtime 154 seconds
Act Net port
To connect the actuator cable and the VVT Zone II
BACnet port
For communication with the controller network using BACnet ARC156 (156 kbps)
or BACnet MS/TP (9600 bps – 76.8 kbps)
Rnet port
•
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.
Local Access port
For system start-up and troubleshooting using Field Assistant
Thermistor inputs
Accepts Precon type II thermistors (10kOhm at 77°F [25°C])
Range: -50°F (-45.5°C) to 250°F (121.1°C)
Dry contact inputs
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.
Voltage inputs
0-5 Vdc. Input impedance is approximately 30 kOhms
Input resolution
10 bit A/D
Binary outputs
3 binary outputs, relay contact rated at 1 A max. @ 24 Vac/Vdc. Configured
normally open.
Analog output
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.
Output resolution
8 bit D/A
Battery
10-year Lithium CR2032 battery retains the following data for a maximum of
10,000 hours during power outages: control programs, editable properties,
schedules, and trends.
