DIO Port
DIO port applies to EMG 8500 only.
The front of the EMG unit has two Digital Inputs and one Relay Output. DIO ports can be used in
Events as a trigger (inputs) or an action (relay output). Specifications for the DIO port:
Two configurable inputs suitable for TTL input levels and tolerant up to 30VDC input voltage.
The DIO inputs can be used to monitor the current status of any attached sensor.
One independently isolated mechanical form-C relay, supporting 1A 24V. When the relay is
energized/turned on, the relay is closed, connecting both relay ports on the I/O connector
through the relay. When the relay is turned off, the signal path is open, disconnecting the relay
ports on the I/O connector.
DIO terminal block (in the UIs the ports are designated as Front #1, Front #2 and Front Relay):
To configure the DIO ports:
1. Change the following Front #1 and Front #2 Input port fields:
