113) The optical coupler inputs respond to a differential
voltage between the two input pins. The signal leg contains a series current-
limiting resistors that were selected to provide between 1.75mA and
13.6mA of LED drive current at voltages of 5 to 28 volts (AC or DC).
The GPI/O has the following limitations:
• GPI Electrical limitations: 24V (max) @13.6mA
• GPO Electrical limitations: 0-100V @ 300mA (max)
Note
The GPO can handle a maximum of 300mA.
