Solid-state Relay (SSR) Outputs
The solid-state relay (SSR) outputs can be used in many applications to switch 24 VAC or 24 VDC on or off for external loads such as actuators, relays, or indicators. SSRs are silent and are not adversely affected by 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 SSR outputs are Form A digital outputs, which means the outputs are normally open contacts with one common terminal and one normally open terminal. The SSR outputs share a common terminal but the outputs can be controlled independently.
