1746sc-OAP8I

The Allen Bradley 1746sc-OAP8I module operates as an isolated circuit discrete output component in the SLC 500 series. This device accommodates eight outputs, each featuring a distinct point assigned to its common. It functions efficiently across a broad voltage spectrum from 74 VAC to 276 VAC, ensuring compatibility with diverse electrical systems. The module is capable of operating within the frequency limits of 47 Hz to 63 Hz, making it suitable for various application requirements.

Each output point can handle a current of 1.5 A at a temperature of 30°C, and this rating diminishes to 1 A when the temperature reaches 60°C. Cumulatively, the total output current rating for the entire module is 9 A at the lower temperature threshold and reduces to 4 A at 60°C. Furthermore, outputs require a minimum load of 5 mA for effective operation, ensuring stability during use. The device features an on-state voltage drop of no more than 1.0 V at 1.5 A, which is critical for maintaining circuit efficiency.

In terms of leakage, the maximum off-state leakage current is capped at 1 mA, indicating that the module maintains a sustainable performance level when inactive. The module’s power dissipation is rated at 9.85 watts, ensuring it operates efficiently within specified parameters. Additionally, the backplane current at 5V is measured at 0.170 A, aligning with standard operational requirements for modules within the SLC 500 series.
