Description Reviews

The Allen-Bradley 1746-IG16 is a 16-channel digital input module engineered for the SLC 500 platform. Designed specifically for low-voltage applications, this module supports 5V DC TTL (Transistor-Transistor Logic) and BCD signal levels. It provides a reliable interface for high-speed electronic sensors, microcontrollers, and encoders that require current-sourcing input capabilities.

Features

Sixteen (16) independent current-sourcing input channels.
Optimized for high-speed response with signal delays of 0.25 ms (ON) and 0.5 ms (OFF).
Integrated electro-optical isolation rated at 1500V AC to protect the SLC backplane from electrical interference.
Compact design for seamless integration into standard SLC 500 chassis configurations.

Applications

This module is ideal for industrial environments where standard 24V DC or 120V AC input modules are unsuitable due to voltage level requirements or switching speed constraints. It is frequently utilized in precision positioning systems, high-speed counting applications, and interfacing with TTL-compatible electronic logic controllers.

Installation Guidelines

Ensure the SLC 500 chassis power is disconnected before installing or removing the module.
Handle the module using proper ESD (electrostatic discharge) prevention practices to protect internal circuitry.
Secure the module firmly into the designated slot in the chassis and tighten the retaining screws to ensure proper backplane connection.
Route signal wiring away from high-voltage cables and heavy inductive loads to minimize electromagnetic interference (EMI).
Verify that the external 5V DC source is within the specified 4.5–5.5V range to ensure correct logic operation.

FAQ

What type of signals does the 1746-IG16 accept?

This module is designed for 5V DC TTL and BCD signals. It acts as a current-sourcing input module, meaning it provides the necessary current to the input device.

Is this module compatible with standard 24V sensors?

No. The 1746-IG16 is specifically rated for 5V DC logic levels. Connecting 24V DC signals will result in damage to the module. Use appropriate voltage level shifting if 24V signals must be interfaced with this module.
