NOMINAL PICKUP AND RESET THRESHOLDS

Nominal battery
voltage
24/27 V Logic 0 < 16.2V, Logic 1 > 19.2V
30/34 Logic 0 < 20.4V, Logic 1 > 24V
48/54 Logic 0 < 32.4V, Logic 1 > 38.4V
110/125 Logic 0 < 75V, Logic 1 > 88V
220/250 Logic 0 < 150V, Logic 1 > 176V
Note:
Filter is required to make the opto-inputs immune to induced AC voltages.
In addition to the above thresholds, some models of this product provide the following threshold levels for FSK
applications:
● For 220/250 voltage inputs: Logic 0 < 145V, Logic 1 > 165V
