Information About 1746-IN16
The 1746-IN16 is part of the Allen-Bradley SLC 500 product family, designed to deliver stable AC/DC input handling for a wide range of control applications. Constructed as a compact single-slot module, it includes built-in LED indicators for each channel, allowing operators to visually verify input status and simplify troubleshooting. It integrates seamlessly with SLC 500 local or expansion chassis and supports standard 1746 I/O connection accessories. Used commonly in machine control, relay monitoring, and general digital sensing tasks, the module employs solid-state input processing with defined signal delays for both AC and DC operation.
Key Features:
- Sixteen input channels: Supports 24 VAC/VDC sinking inputs for broad device compatibility.
- LED status indicators: Provides per-channel visual diagnostics for easy troubleshooting.
- Single-slot design: Fits any SLC 500 chassis slot except reserved processor positions.
- Defined signal timing: 15 ms delay for DC inputs and 25 ms for AC inputs.
- Standard wiring interfaces: Compatible with 1746-HT and 1746-HCA connection hardware.
- Low power consumption: Requires only 85 mA at 5 VDC from the backplane.
- Robust construction: Designed for general-purpose industrial environments.
The 1746-IN16 delivers the reliability and precision required for SLC 500 discrete input monitoring applications.
