GPIO-1 SETUP AND USE

Output Connectors

Sixteen parallel outputs are provided on the GPIO-1 as well as Isolated and Chassis Ground connections. Each output is able to accept

either an external positive voltage between 4 and 30V or use the 24V DC 100mA reference voltage provided on the unit. The 24V DC

supply for use with the Aux Power port is not provided with the unit and will need to be sourced locally. Outputs will be monitored for short

to ground, short to supply and if High Range - Monitored is being used, open circuit conditions will be monitored as well. Consideration

should be given to the state of the output when network connectivity is lost. A Voltage Monitor (VM) input is provided in order that a short

to supply reference voltage is incorporated in output Fault monitoring. A voltage of between 4 - 30V is required by the VM input in order for

the outputs to operate.

If the GPIO-1 Outputs are using a High Range Monitored type of circuit the VM input must match or be greater than the highest Output

Voltage being used. If a higher Voltage is seen on the Outputs compared to the VM Input a Short to Supply fault will be indicated.
