COMMUNICATION

Analog Output

Analog outputs can be used, for example, to operate valve or
damper actuators.
Technical specification
• 3 analog outputs
• Analog output (AO1, AO2, and AO3) details
- Voltage: 0-10 V
- Current: max. 10 mA
- Resolution: 12-Bit
- Min. Step: 2.4 mV
- Accuracy: +/- 100 mV
• AO3 (terminal labeled LED) can be used for Wall Module
LED.

Digital Output

The digital outputs are switched by Triac and can be
connected directly to the external relay- the loads are powered
from digital outputs.
Technical specification
• 6 digital outputs, 4 are free while 2 (DO 1 and DO 2) are
internally connected to the integrated actuator
• Output stages:
- Low signal - 0 V
- High signal - 24 VAC
- Type - Triac
• Load per output:
- min. 30 mA
- max. 500 mA
• Non-isolated within 6 digital outputs (first 2 are reserved
internally to drive the integrated actuator)

Integrated Actuator

There is an actuator vertically integrated with the CPO-VAV2A
controller centre in-line. The power supply and digital outputs
to the integrated actuator are internally provided by the CPO-
VAV2A controller, no need of additional wiring to the
integrated actuator from outside of the CPO-VAV2A controller.
Technical specification
• Type: Non Spring Return, Low Torque, Direct Coupled
Actuator (NSR, LT, DCA)
• Control Scheme: Series 60
• Torque Rating: 5 Nm
• Stroke Rating: 95°
• 90° Stroke Timing: 110 +/- 3 sec @ 50Hz, 90 +/- 2 sec @
60Hz
EN1B-0022 IE10 R0717
• Support declutch mechanism to allow the installer to
manually open or close the VAV box damper without
power or software tool
• Shaft adapter: support different round (8 to 16 mm) or
square (6 to 13 mm) shafts
• Noise (dBA at 1 meter maximum): 35
Attention
The actuator cannot be detached from the CPO-
VAV2A controller.
Avoid mounting the CPO-VAV2A in areas where
acid fumes or other corrosive vapors can attack
the integrated actuator's metal parts, or in areas
where escaping gas or other explosive vapors are
present.
Communication

BACnet MS/TP

The CPO-VAV2A controller has one BACnet MS/TP port.
MSTP connection is internally looped in T-terminal and
remains looped after T-terminal is unplugged from the CPO-
VAV2A controller.
MSTP Channel
Shied should be continuous
