The Allen-Bradley 1756-OA8E is a ControlLogix discrete output module. This module comes with Eight (8) output channels that delivers a nominal output voltage of 120 VAC with operating range of 74-132 VAC, 47-63 Hz. This module has Two (2) output groups of Four (4) channels each with output current of 2 A @ 60 degrees C (140 degrees F) and output current per group of 2 A @ 60 degrees C (140 degrees F); 4 A @ 30 degrees C (86 degrees F) / 2 A @ 60 degrees C (140 degrees F) with linear derating and output current per module of 8 A @ 30 degrees C (86 degrees F) / 4 A @ 60 degrees C (140 degrees F) with linear derating.
The 1756-OA8E has an output delay time of 9.3 ms @ 60 Hz or 11 ms @ 50 Hz for Off to On and On to Off output transitions. This module may be installed to any available slot of the 1756 chassis with a current draw of 200 mA @ 5.1 VDC and 250 mA @ 24 VDC and total backplane power requirement of 7.02 Watts. It has a maximum power dissipation of 5.5 Watts @ degrees C (140 degrees F) and Thermal dissipation of 18.76 BTU/hr.
