Allen-Bradley/Rockwell Automation 1771-OC DC Output Driver Module

The 1771-OC  by Allen Bradley can function in a temperature range of 0 to 60 degrees Celsius; best stored in a zone within -40 and 85 degrees Celsius, its noncondensing relative humidity can hang between 5% and 95%.

With an output current rating of 1.5 A per output, a maximum OFF-State leakage current of 1 mA per output, and a maximum ON-State voltage drop of 2 Volts DC, this module can withstand 1500 Volts of AC power for 60 seconds at a time as determined by tests. Its ESD immunity is contact discharges of 4 kV with air discharges around 8 kV. Dissipating power between 0.9 and 16.9 (minimum and maximum) Watts, its Thermal dissipation hangs between 3.0 and 57.6 (minimum and maximum) BTU an hour.
