The 1746SC-IB8I model from Allen Bradley serves as an isolated circuit-type input module within the SLC 500 series, characterized by its capacity to accommodate 8 inputs. Each input can be configured to function either as a sink or source, granting versatility for various system configurations. The module is rated for a nominal voltage of 24 VDC, with an operational range from ±11.5 to 32 VDC to ensure compatibility with different voltage sources.

Each input is designed to draw a nominal input current of 12 mA at 24 VDC, while maintaining a low offstate current of 1.8 mA, contributing to efficient operation. Power dissipation is rated at 3 watts when operating under standard conditions of 24 VDC, optimizing performance without excess heat generation. The isolation voltage of 1500 VAC enhances safety by preventing electrical interference that might disrupt module function.

Environmental specifications for the 1746SC-IB8I module indicate it can operate effectively in temperatures from 0 to 60 degrees Celsius while supporting storage temperatures from -40 to 85 degrees Celsius, making it suitable for diverse settings. This input module is also equipped to handle relative humidity levels of 5 to 95% without condensation, allowing for reliable operation in various atmospheric conditions. Each of the inputs has individual isolation, with points per common set at 1, ensuring that the performance of one input does not affect the others.
