Industry Trends in Digital Output Modules
The demand for reliable digital output modules continues to grow as industrial automation systems require robust control of high-current loads. The Allen-Bradley 1746-OX8 addresses this need with individually isolated relay contacts, making it suitable for applications where isolation and high current handling are critical. As factories upgrade legacy SLC 500 systems, this module remains a key component for maintaining operational continuity.
Introducing the 1746-OX8
When engineers need a digital output module for high-current relay applications, the Allen-Bradley 1746-OX8 offers a proven solution. Part of the SLC 500 series from Rockwell Automation, this module provides 8 N.O. relay contact outputs with an operating voltage range of 5-265 Volt AC or 5-125 Volts DC. It is designed for individually isolated, high-current relay tasks, ensuring reliable switching in demanding industrial environments.
Technical Specifications Analysis
The 1746-OX8 module delivers a current per output of 3 amps at 120 VAC and 1.2 amps at 24 VDC, with a backplane current consumption of 85-90 milliamps. Its step response is 60 milliseconds in and 2.5 milliseconds out, and it withstands an operating shock of 10 g. These specifications make it well-suited for applications requiring fast, reliable switching under mechanical stress.
Application Scenarios and Use Cases
In manufacturing facilities, the 1746-OX8 can control motor starters, solenoids, and other high-current loads where isolation between outputs is essential. For example, in a packaging line, each relay output can independently manage a different actuator, reducing wiring complexity and improving system reliability. The module's ability to handle both AC and DC voltages adds flexibility for mixed-voltage environments.
Compatibility and Integration
The 1746-OX8 integrates seamlessly into SLC 500 chassis, supporting standard backplane communication. It is compatible with various SLC 500 processors and can be used in systems requiring up to 8 individually isolated relay outputs. For integration details, please refer to official Allen-Bradley documentation or contact Petro Auto Tech.
