Allen Bradley 1756-OA8E Electronic Fused AC Output Module

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. There is no limit to the number of instances of the 1756-OA8E. Instances of this module may be installed to any available slots of the 1756 chassis. It is also provided with individual channel protection as each channel of the module comes with electronic fusing. For connection or signal wires, the 1756-OA8E require use of 1756-TBNH or 1756-TBSH Removable Terminal Block (RTB).
