Concept
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
Pulse width modulated output
Tristate output
Tristate pulsed output
Consider the expected number of operation cycles specified for the relay output (cycle life rating) when configuring the period for a pulse width modulated (PWM) output point.
Outputs
The DO relay outputs are Form A digital outputs, which means the outputs are normally open contacts with one common terminal (C) and one normally open terminal (NO). The terminals are isolated from other circuits of the device and from signal ground.
Three Form A relays share a common terminal but the outputs can be controlled independently.
