24 Vdc terminal
Supplies 24 Vdc to external I/O devices, max 100 mA
Universal output
This output can be set by a DIP switch as an Analog or Binary output.
•
In Analog mode, the output can be used for 0-10 Vdc or a 12 Vdc pulse width
modulated (PWM) control signal at a frequency of 80 Hz.
•
In Binary mode, the output has a built-in relay and can be used to switch
external devices or relays up to 3.75A, 30 Vac/Vdc.
Analog outputs
2 analog outputs, 0
–
10 Vdc (10 mA max)
Binary outputs
2 banks of bussed outputs, 3 N.O. binary outputs per bank. Each relay contact
rated at 3.75 A max. @ 30 Vac/Vdc. Each bank is limited to Class 2 requirements
of 100 VA / 4.2 A. Configured normally open.
See
Output values
(page 30).
Output resolution
12 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 ±3% of sensor
reading at 2 in. H2O.
Controller microprocessor
32-bit ARM Cortex-A8, 600MHz, processor with multi-level cache memory
Memory
4 GBs eMMC Flash memory and 256 MB DDR3 DRAM (2 MB available).
User data is archived to non-volatile Flash memory when parameters are changed,
every 90 seconds, and when the firmware is deliberately restarted.
NOTE
When you change a parameter, you must wait 30 seconds before turning
the power off, in order for the change to be saved.
Real-time clock
Real-time clock keeps track of time in the event of a power failure for up to 3 days.
Protection
A single fast acting, 5mm x 20mm glass fuse for power
The power and network ports comply with the EMC requirements EN50491-5-2.
CAUTION
To protect against large electrical surges on serial EIA-485
networks, place a PROT485 at each place wire enters or exits the building.
