1746-OBP16 SLC 500 16-Point DC Output Module by Allen-Bradley

Product Overview

The 1746-OBP16 is a digital DC output module from Rockwell Automation. It belongs to the SLC 500 product family. This module provides sixteen discrete output channels. It uses a sourcing configuration for 24VDC loads. Each output can handle up to 1.5 amps. The total module current is 6.4 amps. A built-in fuse protects against short circuits. The module fits into a single slot of an SLC 500 chassis. It works with both fixed and modular hardware styles.

Application Scenarios

This module controls industrial actuators and relays. It is ideal for high-current DC loads. Use it in manufacturing and packaging lines. It works well in material handling systems. The 1746-OBP16 also suits automated assembly machines. Its fast response time supports precise control. The sourcing output is common in North American panels. The module integrates easily with existing SLC 500 systems.
