Description

Allen-Bradley 1746-IB16 Input Module

Product Dimensions：

The Allen-Bradley 1746-IB16 is a discrete input module belonging to the SLC 500 family of Programmable Logic Controllers (PLCs). It is a highly reliable, high-density digital input module designed to interface with various field devices.

1. Product Description

The 1746-IB16 is a 16-channel sinking DC input module. It operates at a nominal voltage of 24V DC and is used to sense the “On/Off” state of devices such as limit switches, float switches, and proximity sensors. As a “sinking” module, it receives current from sourcing field devices.

2. Technical Specifications

3. Key Advantages

• High Density: Provides 16 input points in a single slot, allowing for smaller chassis sizes and reduced system costs.

• Reliability: Built with industrial-grade components to withstand harsh factory environments.

• Easy Maintenance: Features a removable terminal block (RTB), allowing you to replace the module without disconnecting the field wiring.

• Status Indicators: Includes clear LED diagnostics on the front panel for each of the 16 channels, making troubleshooting much faster.

4. Important Considerations (Precautions)

• Sinking vs. Sourcing: Ensure your field devices are sourcing (PNP). Using the wrong wiring polarity will result in the module failing to detect signals.

• Voltage Limits: Do not exceed 30V DC. Overvoltage can cause permanent damage to the internal optocouplers.

• Heat Dissipation: When using multiple high-density modules in one chassis, ensure there is adequate ventilation to prevent overheating.

• Electrostatic Discharge (ESD): Always wear a grounding wrist strap when handling the module to prevent damage to the sensitive CMOS circuitry.

5. Product Applications

The 1746-IB16 is widely used in discrete manufacturing and process control, including:

• Conveyor Systems: Monitoring sensors for box detection and belt alignment.

• Packaging Machinery: Interfacing with push buttons, limit switches, and safety interlocks.

• Automotive Assembly: Tracking the position of pneumatic cylinders or robotic arms.

• Food and Beverage: Detecting bottle presence or valve positions in filling lines.
