The Allen-Bradley 1756-OB8 is a versatile ControlLogix discrete output module that offers an output voltage range of 10-30 VDC, with a nominal value of 24 VDC, making it ideal for energizing both DC and AC loads through interposing circuitry. This single-slot module integrates seamlessly into any available 1756-ControlLogix chassis slot except the left-most, supporting both local and distributed I/O configurations. It features a backplane current draw of 165 mA at 5.1 VDC and 2 mA at 24 VDC, with a total backplane power of 0.89 W, and efficiently handles up to 2 Amperes per channel and 8 Amperes per module at 60°C, making it a reliable choice for demanding applications requiring high operational efficiency and robust thermal management.
