Triac Outputs; Analog Outputs - Distech Controls ECLYPSE Installation Manual

Triac Outputs

Triac outputs provide either high voltage (ECY-PTU-107/207: same voltage as power supply (100-240VAC) – 0.5 A max. per output) or low voltage
(ECY-PTU-208 / ECY-TU-203: 24 VAC - 600 mA aggregate for the total of the outputs, including 24V~ outputs)).
Triac outputs can be used to turn equipment and devices on and off (two-state outputs) and to control valve and damper actuators using Pulse Width
Modulation (PWM).
£ Triac output connectors accept wires between 1 mm² (17 AWG) and 1.5 mm² (16 AWG). Make sure the cable performances suit the connected
loads.
£
To measure the state of a triac output, an external load must be connected.
£
For ECY-PTU-208, it is not necessary to use a fuse when the onboard 24 VAC output is being used with the triac outputs since it already has a built-
in short circuit protection.
£
For ECY-PTU-208 and ECY-TU-203, if functional Earth is connected, triac output circuits will be PELV. If functional Earth is NOT connected, triac
output circuits will be SELV.

Analog Outputs

Analog outputs are configured to provide a linear signal ranging from 0 to 10 VDC.
£ Analog output connectors accept wires between 0.75 mm² (18 AWG) and 1.5 mm² (16 AWG).
£
If an analog actuator is being controlled, connect the 0 to 10 VDC output, along with an external 24 VAC power source, to the analog actuator.
£
For ECY-PTU-208 and ECY-TU-203, the onboard 24 VAC power supply can be used to power 0-10 V actuators.
£
If functional Earth is connected, analog output circuits will be PELV.
£ If functional Earth is NOT connected, analog circuits will be SELV.
Control Output Type
£
0 to 10VDC voltage output.
£
0 to 10VDC voltage output controlling an analog actuator powered by
an external 24VAC power source.
£ 0 to 10VDC voltage output controlling an analog actuator powered by
the controller (ECY-PTU-208 and ECY-TU-203 models)..
