Notes:
Meets cULus requirements without the need of an
electrical ground connection
Actuators may be connected in parallel. Power
2
consumption and input impedance must be observed.
Actuators may also be powered by 24 VDC.
3
Control signal may be pulsed from either the Hot
8
(Source) or Common (Sink) 24 VAC line.
Contact closures A & B also can be triacs. A & B should
both be closed for the triac source and open for triac
9
sink.
For triac sink the Common connection from the actuator
must be connected to the Hot connection of the
controller. Position feedback cannot be used with a triac
10
sink controller. The actuator internal common reference
is not compatible.
IN4004 or IN4007 diode. (IN4007 supplied)
12
Actuators with plenum rated cable do not have numbers
18
on wires; use color codes instead.
