Optoisolated
Input Ratings
250 Vdc: on for 200 - 300 Vdc; off below 150 Vdc
125 Vdc: on for 105 - 150 Vdc; off below 75 Vdc
48 Vdc: on for 38.4 - 60 Vdc; off below 28.8 Vdc
24 Vdc: on for 16.0 - 30 Vdc.
With nominal control voltage applied, each optoisolated input draws approximately
4 mA of current.
