COMMUNICATION
EN1B-0022 IE10 R0717 10
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
• 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
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.

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.
