Description

The Allen-Bradley 1746-OVP16 is a high-density discrete output module designed for the SLC 500 programmable controller platform. This module is specifically engineered for high-current applications requiring a sinking configuration, providing 16 output points that act as the ground side of the circuit for 24V DC field devices. The 'P' designation signifies enhanced power handling capabilities and integrated protection features, ensuring reliable operation in demanding industrial environments.

Features

  • 16 sinking output points for 24V DC field devices.
  • High-current output capability for robust industrial switching.
  • Integrated fuse protection for circuitry safety.
  • Blown fuse LED indicator on the front panel for rapid diagnostic troubleshooting.
  • Removable Terminal Blocks (RTBs) for simplified wiring and efficient module replacement without disturbing field connections.

Applications

This module is intended for use in SLC 500 chassis-based systems. It is commonly deployed in manufacturing and process control environments for driving high-current DC loads such as solenoids, relays, and contactors where sinking output logic is required.

Installation Guidelines

  • Ensure the SLC 500 chassis power is disconnected before installing or removing the module to prevent electrical arcing or damage.
  • Use the provided Removable Terminal Blocks (RTBs) for wiring; ensure wires are properly secured to prevent intermittent connections.
  • Maintain adequate clearance around the module to allow for proper ventilation and heat dissipation.
  • Follow standard ESD (Electrostatic Discharge) handling procedures when touching internal module components.
  • Route signal wiring away from high-voltage AC lines or high-EMI sources to minimize signal interference.

FAQ

Does this module require external power for the outputs?

Yes, the 1746-OVP16 requires an external 24V DC power source to drive the field devices connected to the sinking outputs.

What does the 'P' in 1746-OVP16 stand for?

The 'P' indicates that the module includes integrated protection features, specifically a fused common and a blown fuse indicator LED, which are not present on standard output modules.
