Allen Bradley 1746-ITB16 SLC 500 Digital Input Module – 16-Channel, 24V DC Sink Inputs, High-Speed Signal Processing
The Allen Bradley 1746-ITB16 is a 16-channel digital input module designed for the SLC 500 automation platform. This module provides 24V DC sinking inputs, making it suitable for integration with NPN (negative switching) field devices. With fast signal response times and reliable noise immunity, the 1746-ITB16 is ideal for general machine control, high-speed sensing, and industrial automation I/O applications.
The module installs directly into any SLC 500 chassis and utilizes screw-terminal field wiring for secure and serviceable industrial connections. It supports detection of rapid signal transitions with input response times as low as 0.3–0.5 ms, ensuring precise event capture in motion, process, and discrete logic control systems.
