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 Bypass 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
You can connect:
One Equipment Touch, using an external 24 Vac power supply
or
One TruVu™ ET Display, using an external 24 Vdc power supply
Local Access port
For system start-up and troubleshooting
Input
1 input for connecting the Duct air temperature sensor (#33ZCSENDAT)
Input resolution
10 bit A/D
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
Integral airflow sensor
Precision differential pressure sensor 0–2 in. H2O, sensitive down to ±0.001 in.
H2O. Barbed tapered airflow connections accept 3/16 in. (4.75 mm) I.D. tubing.
Allows for readings across the 0–2 in. H2O range, accurate to ±5% of full flow at 2
in. H2O.
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.
Protection
Built-in surge and transient protection for power and communications in
compliance with EN61000-6-1.
Incoming power and network connections are protected by non-replaceable
internal solid-state polyswitches that reset themselves when the condition that
causes a fault returns to normal.
The power, network, input, and output connections are also protected against
transient excess voltage/surge events lasting no more than 10 msec.
CAUTION
To protect against large electrical surges on serial EIA-485
networks, place a PROT485 at each place wire enters or exits the building.
BT485 connector
You attach a BT485 (not included) to a controller at the beginning and end of a
network segment to add bias and to terminate a network segment.
