1756-OA8E Functional Description  

The Allen-Bradley 1756-OA8E is a ControlLogix discrete output module designed to deliver reliable and efficient control of output signals. With eight (8) output channels, this module provides a nominal output voltage of 120 VAC, with an operating range of 74-132 VAC and a frequency of 47-63 Hz. The 1756-OA8E ControlLogix discrete output module features two groups of four channels, each capable of handling 2 A at 60°C (140°F), with a maximum combined output current of 8 A at 30°C (86°F) and 4 A at 60°C (140°F), ensuring flexibility for various industrial applications.

This module is optimized for high performance with a fast output transition time of 9.3 ms at 60 Hz and 11 ms at 50 Hz, ensuring quick and reliable switching between On and Off states. It draws 200 mA from the 5.1 VDC backplane and 250 mA from the 24 VDC supply, requiring a total backplane power of 7.02 W. Additionally, the 1756-OA8E ControlLogix discrete output module has a power dissipation of 5.5 W and thermal dissipation of 18.76 BTU/hr, making it efficient in managing heat during operation.

Each output point on the 1756-OA8E ControlLogix discrete output module is protected by electronic fuses, providing robust individual channel protection. The module has a maximum leakage current of 3 mA per point in the off state and supports a surge of 20 A for 43 ms every 2 seconds. The 1756-OA8E ControlLogix discrete output module is compatible with the 1756-TBNH or 1756-TBSH Removable Terminal Block (RTB) for signal connections.

Certified for both CE and UL standards, the 1756-OA8E ControlLogix discrete output module operates optimally in temperatures ranging from 0°C to 60°C, with a storage range between -40°C to 85°C, making it suitable for a variety of industrial environments.
