Descripción Reseñas

The Allen-Bradley 1746-IH16 is a high-density DC digital input module designed for use within the SLC 500 programmable controller system. This 16-point input module is engineered for current-sinking applications, providing reliable signal monitoring for industrial automation processes requiring 125V DC logic levels.

Features

16 isolated input channels for high-density signal integration.
Supports a voltage range of 90-146V DC (sinking configuration).
Optimized signal delay of 9 milliseconds for stable input processing.
Low off-state current of 0.8 milliamps to prevent false triggering.
Compact SLC 500 form factor for efficient rack-space utilization.

Installation Guidelines

Ensure the SLC 500 rack power is disconnected before installing or removing the module.
Insert the module into any available slot in the SLC 500 chassis; ensure the module is fully seated and the locking tab is engaged.
Verify that wiring is routed away from high-voltage AC lines or high-EMI sources to minimize signal noise.
Use appropriate wire gauges and ensure all terminal connections are secure to prevent intermittent contact.
Maintain adequate airflow around the chassis to prevent overheating during continuous operation.

Applications

This module is suitable for various industrial monitoring tasks in the SLC 500 ecosystem, including interfacing with high-voltage DC sensors, proximity switches, and control panel pushbuttons that require a sinking input configuration.

FAQ

Is the 1746-IH16 compatible with standard SLC 500 racks? Yes, this module is designed specifically for the Allen-Bradley SLC 500 modular I/O chassis.

What is the primary function of the sinking input? A sinking input module provides the common return path for the input circuit, meaning the field device must switch the positive side of the DC supply to the input terminal.
