Description

The Allen-Bradley 1746-OBP16 is a high-current sourcing DC output module designed for the SLC 500 programmable logic controller system. This module provides 16 output points, enabling the control of various DC-powered field devices such as solenoids, contactors, and indicators. As a sourcing output module, it supplies the positive voltage to the load, making it suitable for applications requiring high-current switching capabilities within an industrial automation environment.

Features

  • 16 sourcing DC output channels for versatile control applications.
  • High-current capacity with a total module current rating of 6.4 Amps.
  • Compatible with the SLC 500 I/O chassis for seamless integration.
  • Designed for standard 24V DC operation (20.4 to 26.4 VDC range).
  • Reliable performance in demanding industrial control tasks.

Applications

This module is typically utilized in manufacturing, material handling, and process control systems where the SLC 500 platform is deployed. It is ideal for driving high-current DC loads that require robust sourcing output protection and reliable switching in a modular PLC architecture.

Installation Guidelines

  • Ensure the PLC system power is disconnected before installing or removing the module from the I/O chassis.
  • Verify that the module is fully seated in the chassis slot and the locking tab is engaged.
  • Use appropriate wire gauges and ensure all terminal connections are secure to prevent intermittent contact.
  • Maintain proper spacing for ventilation to prevent overheating during high-current operation.
  • Follow standard ESD (Electrostatic Discharge) handling procedures when touching internal components or connectors.
  • Ensure that the load current does not exceed the specified per-output or total module limits to prevent damage to the output circuitry.

FAQ

Is the 1746-OBP16 still in production?

No, this module has been discontinued by the manufacturer. We provide high-quality surplus units to support legacy SLC 500 systems.

What does "sourcing" mean for this output module?

A sourcing output module provides the positive voltage (VDC+) to the connected load, while the load is connected to the common return (VDC-).
