Act Net port
Supports a combination of up to 5 Act Net addresses, as follows:
•
Address
1
is reserved for the Carrier actuator
•
Address
2
and
3
are reserved for the VAV Zone II Secondary Duct
•
Address
4
and
5
for i-Vu® Smart Valves
Maximum power available for Act Net devices:
•
AC supply - 25 VA (1 A)
•
DC supply - 15W (0.625A)
•
Use an external transformer if your devices exceed the maximum power.
Service port
USB 2.0 host port for setting up the controller and troubleshooting through a local
connection to a computer, connecting to the TruVu™ ET
Display, or the Carrier
wireless service adapter.
USB Comm port
For future use.
Universal inputs
6
Inputs are configurable in the control program for 0
–
5 Vdc, 0
–
10 Vdc, thermistor,
dry contact, or pulse counter.
Input resolution
12 bit A/D
Input pulse frequency
10 pulses per second. Minimum pulse width (on or off time) required for each
pulse is 50 msec.
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.
Binary outputs
2 banks of bussed outputs, 3 N.O. binary outputs on one bank, 2 N.O. binary
outputs on the other. 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 27).
Output resolution
12 bit D/A
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.
