Triac Outputs
The triac outputs can be used in many applications to switch 24 VAC on or off for external loads such as actuators, relays, or indicators. Triacs are silent and do not suffer from relay contact wear.
The outputs can be configured as one of the following types:
Digital output
Digital pulsed output
Pulse width modulated output
Tristate output
Tristate pulsed output
Outputs
The DO triac outputs are designed to switch 24 VAC. The common terminal COM can be connected to 24 VAC or to ground. DO1, DO2, and DO3 share the common terminal COM. The terminals are opto-isolated from the controller.
R V1 and R V2 are varistors (95 V, 2 J) for protection of the triac.
R 1 = 47 ohm
C 1 = 22 nF
Optionally, to protect the triac outputs from damage in the event of external wiring short circuit, you can connect an in-line fuse (3 A) in series with the COM terminal.
