The Allen Bradley 1771-OBDS is a robust DC Current Limiting Output module equipped with 16 outputs, engineered for demanding industrial applications. This module features a maximum on-state voltage drop of 1.5 volts and a minimal off-state leakage current of 0.5 mA per output, ensuring efficient performance. Its power dissipation ranges from 2 to 14 watts, while thermal dissipation varies between 6.9 and 47.8 BTU/hour. Designed for reliability across a broad operating temperature range of 0 to 60 degrees Celsius, and withstanding non-operating conditions between -40 to 85 degrees Celsius, it effectively handles varying environmental stresses. The unit is tested for a 500-volt isolation voltage and exhibits robust ESD immunity, supporting 4 kV contact discharges and 8 kV air discharges. It is classified as open type equipment suitable for Zone 2 environments with Pollution Degree 2, necessitating careful installation and inspection prior to operation.
