The 1756-OH8I is a high-performance DC digital output that belongs to the ControlLogix series.  Manufactured by Allen-Bradley, this module features 8 isolated 120 Volts DC sinking or sourcing outputs that are available on its chassis. Its voltage rating ranges from 90 to 146 Volts DC. This module’s output signal delay time is 2 milliseconds while its backplane draws current at 24 Volts is 2 milliamps (mA) and 210 milliamps at 5.1 Volts. Its overall backplane power is 1.1 Watts. When operational, the 1756-OH8I dissipates 3.3 Watts of heat at 60 degrees Celsius (140 degrees Fahrenheit).  Besides, the module features an OFF-state leakage current rating of 1 milliamps per point.

When operational, the 1756-OH8I possesses a drop voltage of 2 Volts DC at 2 Amps and the peak current retained on every output terminal is 2 Amps.  The maximum amount of current that the 1756-OH8I can sustain is 8 Amps at 60 degrees Celsius, while the minimum current load at each point is 2 mA with a surge of 4 Amps.  The module’s isolation voltage between the backplane and the outputs is about 250 Volts with the standard insulation tested at 1350 Volts AC for 2 seconds. In addition, the 1756-OH8I has a T4A (North America) temperature code and it is enclosed in an open-type chassis. Its operating temperature varies from 0 to 60 degrees Celsius at an environment featuring 5 to 95% relative humidity. The 1756-OH8I is uniquely designed to withstand a maximum operational shock rating of 20G and a vibration of 2G at 10 to 500 Hertz. The 1756-OH8I is highly resistant to shock and it can sustain an operational vibration of 2G. Plus, the module offers excellent performance.
