Excellent PLC
Product Introduction
The Allen Bradley 1746-IA8 SLC 500 AC Digital Input Module is an 8-channel AC input module designed for integration within the SLC 500 automation platform by Rockwell Automation. It is built to reliably detect and transmit AC input signals from field devices to the controller, ensuring stable monitoring of discrete processes.
This module operates with 100/120 VAC input signals, making it suitable for applications where AC-powered devices such as push buttons, limit switches, and relays are commonly used. Its open-style design allows for efficient heat dissipation while maintaining dependable operation in standard industrial control cabinets.
With 8 input points grouped for simplified wiring, the 1746-IA8 provides a practical and cost-effective solution for systems that require AC signal acquisition within SLC 500 rack-based architectures.
