About 1756-OH8I
Allen-Bradley's 1756-OH8I ControlLogix DC digital Output module is a digital output module with eight isolated 120V DC feed/pull current outputs on the chassis of ControlLogix devices. It has a voltage range of 90-146V DC and a maximum output signal delay time of 2ms ON to OFF and OFF to ON. The 1756-OH8I has a backplane current consumption of 2mA at 24V and 210mA at 5.1V for a total backplane power of 1.1W. In operation, it emits 3.3W (11.25 BTU/hr) of heat at 60 °C (140 °F) and has a turn-off leakage current of 1mA per point. In the on-state, the 1756-OH8I has a voltage drop of 2V DC at 2A, and the maximum current retained at each output point is 2A. With a minimum current load of 2mA per point and a surge of 4A per point, the 1756-OH8I module can withstand a maximum current of 8A at 60 °C (140 °F).
Its isolation voltage between output to backplane and output to output is 250V, and the basic insulation type was tested for 2 seconds at 1350V AC. The 1756-OH8I has a factory specified T4A North American temperature code and comes with an open housing. It has an operating temperature range of 0-60 °C (32-140 °F) at 5-95% relative humidity. The 1756-OH8I is designed to withstand operating vibrations of 2G at 10-500Hz and shock ratings of up to 20G.
