製品紹介
The Allen Bradley 1746-IN16 SLC 500 Digital Input Module is a reliable 16-channel digital input module designed for use within the SLC 500 control system family by Rockwell Automation. It is engineered to monitor field signals from various AC/DC input devices and transmit accurate status information to the programmable controller.
This module supports both 24V AC and DC input signals, making it highly adaptable in mixed-signal environments. With 16 input points grouped per common, it simplifies wiring while maintaining signal integrity. The design ensures stable signal acquisition even in electrically noisy industrial settings, which is critical for maintaining control system reliability.
Widely deployed in legacy and ongoing automation systems, the 1746-IN16 remains a practical choice for maintaining and expanding existing SLC 500 installations where proven stability and compatibility are essential.
