Specifications
Driver
drv_bpopen_x-xx-xxx
Power
24 Vac ±10%, 50–60 Hz
14 VA power consumption
26 Vdc (25 V min, 30 V max)
Single Class 2 source only, 100 VA or less
BACnet port
For communication with the controller network using BACnet ARC156 (156 kbps)
or BACnet MS/TP (9600 bps – 76.8 kbps)
Rnet port
For connecting an Equipment Touch
Local Access port
For system start-up and troubleshooting
Inputs
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 low flow AWM series 0–2 in. H20 (0-.498 kPa), sensitive down to
±0.001 in. H
2
0 (±.00025 kPa). Barbed tapered airflow connections accept 3/16
in. (4.75 mm) I.D. tubing. Allows for readings across the 0–2 in. H
2
0 (0 - .498 kPa)
range, accurate to ±5% of full flow at 2 in. H
2
0 (.498 kPa).
Integral actuator
Brushless DC motor, torque 35 inch-pounds (4 Nm), runtime 205 seconds for 90
degree travel during control, or 25 seconds in high-speed test and balance mode
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
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.
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.
Status indicators
LED's indicate status of communications, running, errors, power, and digital
outputs
Environmental operating

Storage temperature range
-24 to 140°F (-30 to 60°C), 0 to 90% relative humidity, non-condensing
Physical
UL94-5VA plenum rated enclosure for installation in plenum (or other space for
environmental air) in accordance with NEC Section 300.22 (c) and (d)
