Output Wiring - Distech Controls ECLYPSE ECY-VAV Installation Manual

Output Wiring

Output options must be properly configured in EC- gfx Program to ensure correct output values. For terminal block connector wiring best practices, see
General Wiring Recommendations
Power may be available from ECY-VAV-PoE controllers to power external loads; see the table below.
Outputs can be connected as follows.
Before connecting an output device (actuator, relay, etc.) to the controller, refer to the datasheet and installation
guide of the equipment manufacturer.
£ For a wire length less than 75' (23m) long, either a shielded or unshielded 18AWG wire may be used.
£
For a wire length up to 200' (61m) long, a shielded 18AWG wire is recommended.
£
The shield of the wire should be grounded on the controller side and the shield length should be kept as
short as possible.
£ Triac outputs are factory set for internal power.
Control Output Type
£
Discrete 0 or 12VDC digital, Pulse, or PWM output controlling a 12VDC
relay.
£ 0 to 10VDC voltage output.
£
0 to 10VDC voltage output controlling an analog actuator that is powered
by an external 24VAC power source.
£ This output can source up to 20 mA
£ 0 to 10VDC voltage output controlling an analog actuator that is powered
by the ECY-VAV-PoE controller's power over Ethernet IEEE 802.3at cer-
tified switch.
£ Power is taken from the controller's power input terminals (24VAC and
24V COM) to power external loads up to 15 Watts total maximum
£
1 to 10VDC voltage output controlling dimmable lighting ballasts that re-
quire a current sink output (pull-down).
£ This output can sink up to 5mA.
£ Discrete digital, Pulse, or PWM output: 24VAC externally-powered triac
