BACNET IP/MSTP VAV - INSTALLATION INSTRUCTION
SPECIFICATIONS
Electrical
Voltage Range:
20-30 VAC; Class 2 transformer
Nominal
Power Consumption:
—
IP variant: 8VA; Controller and actuator load (nothing
connected to IO's and COM)
—
MSTP variant: 6VA; Controller and actuator load (nothing
connected to IO's and COM)
Full Load Power Consumption:
—
IP variant: 30VA; Maximum load including external loads
(including SYLK™, communication, BLE, UIO output, 20V output)
—
MSTP variant: 22VA; Maximum load including external loads
(including SYLK™, communication, BLE, UIO output, 20V output)
—
If SSR is used it should consider real VA needed.
Frequency Range:
50 to 60Hz
Auxiliary Output:
20 VDC @ 75 mA
Hardware
CPU:
Crossover processor NXP I.MRT, Cortex M7
Memory capacity:
16MB QSPI Flash, 16MB SDRAM
Ethernet:
2 X RJ-45 Ethernet ports with integrated fail- safe for
daisy-chaining
Real Time Clock:
24-hr backup after power failure. The
controller includes a supercapacitor to power the built-in real
time clock for 24 hours. In case of power failure, the super
capacitor retains the time set in controller for 24 hours. After
24 hours, the time will reset to default factory time until user
perform BACnet Time Sync.
Communication

BACnet IP (IP variants), BACnet MSTP
(MSTP variants), Sylk™, Modbus Master / Slave (different
order numbers).
Ethernet Connection Speed:
10/100 Mbps
Addressing:
IPv4
BACnet Profile:
B-AAC
Sylk™ Bus:
2-wire, polarity-insensitive
