Connecting devices to Digital Outputs
Depending on the controller model, 2 to 8 Digital Outputs are available for multiple pur-
poses. The Outputs are Open Drain MOSFET outputs capable of driving over 1A at up to
24V. See datasheet for detailed specifications.
Since the outputs are Open Drain, the output will be pulled to ground when activated.
The load must therefore be connected to the output at one end and to a positive voltage
source (e.g. a 24V battery) at the other.
Connecting Resistive Loads to Outputs
Resistive or other non-inductive loads can be connected simply as shown in the diagram
