Digital I/O Connector
The Digital I/O connector has 4 GPIO connections plus 1 Return connection. The Digital I/O supports Both
Dry and Wet contacts up to 60Volts.
• Dry contact is isolated from a voltage source (or "No Volt"), with an embedded relay function (NPN
• Wet contact is a contact with external power (+3.3V to +60V, max 150mA of current allowed at high
Figure 7
Note Digital I/O is only supported on IOS-XE version 16.12.1 and above.
Note
The default state of the Digital I/O is input, the open-collector is open (off).
