Wiring Diagrams

1

Provide overload protection and disconnect as required.

3

Actuators may also be powered by 24 VDC.

4

Position feedback cannot be used with Triac sink controller.
The actuator internal common reference is not compatible.

5

Control signal may be pulsed from either the Hot (source)
or the Common (sink) 24 VAC line.

8

Contact closures A & B also can be triacs.
A & B should both be closed for triac source and open for triac sink.

9

For triac sink the common connection from the actuator
must be connected to the hot connection of the controller.

Meets UL requirements without the need of an electrical ground
connection.
