The Allen Bradley 1771-OBNK, part of the PLC 5 output module series, is a robust digital DC output module featuring 32 outputs arranged in groups of four with each group comprising eight outputs. It operates efficiently within a temperature range of 32 to 140 degrees Fahrenheit and can be stored between -40 and 185 degrees Fahrenheit, sustaining relative non-condensing humidity levels from 5 to 95%. With a 1500 Volts AC RMS isolation voltage and a maximum output voltage of 30 Volts DC at 0.5 A per output, it ensures reliable performance, while its durable design includes four 4.0 A, 250 Volt fuses, each serving a group of outputs, and it maintains a minimal ON-state voltage drop of 1.4 Volts DC under load conditions.
