Relay Outputs
The relay outputs support digital Form A point types. The Form A relays are designed for direct load applications.
The outputs can be configured as one of the following types:
Digital output
Digital pulsed output
Tristate output
Tristate pulsed output
Outputs
The DO relay outputs are Form A digital outputs, which means the outputs are closing contacts with one common terminal (C) and one normally open terminal (NO). The terminals are isolated from signal ground.
