Optoisolated Inputs
Contact inputs have a fixed, 1/4-cycle debounce time
250 Vdc: Pickup 200–300 Vdc; Dropout 150 Vdc
220 Vdc: Pickup 176–264 Vdc; Dropout 132 Vdc
125 Vdc: Pickup 105–150 Vdc; Dropout 75 Vdc
110 Vdc: Pickup 88–132 Vdc; Dropout 66 Vdc
48 Vdc: Pickup 38.4–60 Vdc; Dropout 28.8 Vdc
24 Vdc: Pickup 15.0–30 Vdc
Note: 24, 48, and 125 Vdc optoisolated inputs draw approx. 4 mA
of current; 110 Vdc inputs draw approx. 8 mA of current; and 220
and 250 Vdc inputs draw approx. 5 mA of current. All current
ratings are at nominal input voltage.
