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.
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.
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.
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.
LEDs indicate status of communications, running, errors, power, and digital
