1746sc-IC8I

The Allen Bradley 1746sc-IC8I functions as an isolated circuit-type discrete input module within the SLC 500 series. This module is engineered to handle discrete inputs while ensuring individual isolation for each point. The design accommodates up to eight inputs that can be assigned as either sink or source, providing flexibility in application setups. Operating within a voltage range from ±30 to 60 VDC, it is versatile in meeting various system requirements.

With a voltage rating set at 48 VDC, this module requires a nominal input current of 10 mA for standard operational scenarios. An offstate current of 1.8 mA can be tolerated, allowing for efficient energy management. Power dissipation is rated at 4 watts when operating within 120 VAC or DC environments. Furthermore, a backplane current of 0.110 A is drawn at 5 VDC, which is critical for maintaining system integrity.

The 1746sc-IC8I features rapid signal processing with a response time of 0.5 milliseconds from off to on and 1 millisecond for the reverse transition, facilitating effective real-time control in various applications. Designed for environments with relative humidity ranging from 5 to 95% (non-condensing), this module is suitable for a range of industrial conditions. Overall, the 1746sc-IC8I is a reliable choice for discrete input applications requiring strict isolation and operational flexibility.
