Description

The Allen-Bradley 1746-OVP16 is a high-density, 16-point discrete output module engineered for the SLC 500 control platform. This module is specifically designed for high-current applications requiring a sinking configuration, where it switches the ground side of 24V DC field devices. The 'P' designation signifies the inclusion of enhanced power handling and integrated circuit protection, ensuring reliable operation in demanding industrial environments.

Features

Sixteen (16) sinking output points.
Integrated protection circuitry featuring an internal fuse for overcurrent prevention.
Visual diagnostics via a front-panel blown fuse LED indicator for rapid fault identification.
Utilizes Removable Terminal Blocks (RTBs) to facilitate efficient wiring and maintenance without disturbing field connections.
Optimized for 24V DC operation with low on-state voltage drop.

Installation Guidelines

Ensure the SLC 500 rack is powered down before inserting or removing the 1746-OVP16 module to prevent electrical arcing or damage to the backplane.
Verify that the module is properly seated in the chassis slot and secured with the top and bottom locking tabs.
Use appropriate wire gauges for the Removable Terminal Block (RTB) as specified by local electrical codes.
Maintain proper clearance around the module to allow for adequate ventilation and heat dissipation.
Follow standard ESD (Electrostatic Discharge) mitigation practices when handling the module to protect internal components.

FAQ

What does the 'P' in 1746-OVP16 represent?
The 'P' indicates that the module includes enhanced power handling capabilities and integrated protection, such as fused commons and blown fuse detection, which are not present in standard non-protected output modules.

Can I replace this module without rewiring the system?
Yes, the 1746-OVP16 utilizes Removable Terminal Blocks (RTBs), allowing you to swap the module body while keeping the field wiring attached to the terminal block.

What is the primary application for this module?
This module is intended for high-current DC loads in SLC 500 systems where sinking configuration is required to control field devices like solenoids, contactors, or indicators.
