Information About 1746-IB16
The Allen-Bradley 1746-IB16 is a medium-density input module used to receive signals from field devices that output 10–30 VDC. With sixteen sinking input channels grouped into a single common, it installs into any slot of an SLC 500 chassis and draws 85 mA at 5 VDC from the backplane. The module supports sinking-type wiring only, making it ideal for interfacing to sourcing field devices such as proximity sensors, pushbuttons, limit switches, and relay auxiliary contacts. Each input channel provides an 8 ms signal delay for both ON and OFF transitions, ensuring stable input detection in electrically noisy environments.
Key Features:
- Sixteen (16) 24 VDC sinking input channels
- Operating voltage range: 10–30 VDC
- Single input group with one common
- 8 ms input signal delay (ON/OFF)
- Optical isolation: 1500 V
- Diagnostic LED indicators for all input points
- Compatible with all SLC 500 chassis
- Supports sourcing field devices
- Removable terminal block for easy wiring
- UL, CSA, and CE certified
The 1746-IB16 is a dependable and widely used digital input module for the SLC 500 family. Offering 16 channels of DC sinking inputs with stable signal filtering and strong noise immunity, it is well-suited for machine automation, material handling, and general manufacturing applications. Its consistent performance, rugged construction, and ease of maintenance make it a staple in existing SLC 500 installations.
