Concept
High Power Relay Outputs
The main application of the high power relay output is to power an electrical heating element directly.
The outputs can be configured as one of the following types:
Digital output
Digital pulsed output
Pulse width modulated 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 high power relay outputs are Form C digital outputs, which means the outputs are switching contacts with one common terminal (C), one normally-open terminal (NO), and one normally-closed terminal (NC). The terminals are isolated from other circuits of the device and from signal ground.
