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.
