Description
Allen-Bradley 1746-ITB16 Technical Overview
The Allen-Bradley 1746-ITB16 is a fast-response discrete digital input module in the SLC 500 series manufactured by Rockwell Automation. Designed for high-speed switching and time-critical applications, this lightweight module weighs approximately 0.23 kg (0.51 lbs) and features 16 sinking input channels operating at a nominal voltage of 24 VDC (10–30 VDC range). It integrates optical coupling and filter circuitry for noise reduction, removable terminal blocks for easy maintenance, and LED status indicators for real-time channel diagnostics across operating temperatures from 0 °C to 60 °C (32 °F to 140 °F).
