Monitor Sensor for network use:

Type: Voltage.

Supported Sensors: Third party 2 to 10V, 2 to 10 volts displayed.

Digital Inputs:

Dry-contact inputs are sensed using a 9 milliamp at 4.8 volts detection circuit. It is very important that the device used contains high quality, noncorroding contacts with resistivity that does not degrade; that is, increase over time. Use noble metal (such as gold or silver) or pimpled or sealed contacts to assure consistent, long-term operation.

Triac Outputs:

Triac Outputs on the RIO:

—Power ratings: 20 Vac to 30 Vac at 25 mA MIN to 500 mA MAX current for any voltage.
