Industry Trends in Digital Output Modules
In modern industrial automation, the demand for reliable and high-current relay output modules continues to grow as facilities upgrade legacy systems. Engineers require components that can handle diverse voltage ranges and provide robust isolation for sensitive control logic. The Allen-Bradley 1746-OX8 addresses these needs with its individually isolated, normally open relay contact outputs, making it a trusted choice for demanding applications.
Introducing the 1746-OX8 Digital Contact Output Module
When designing or maintaining a SLC 500 control system, selecting the right output module is critical for ensuring uptime and safety. The Allen-Bradley 1746-OX8 is a digital contact output module that offers 8 N.O. relay contact outputs, each individually isolated for high-current relay applications. Its operating voltage spans 5-265 Volt AC or 5-125 Volts DC, providing flexibility across various industrial power systems.
Technical Specifications Analysis
The 1746-OX8 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, ensuring reliable switching in time-sensitive processes. The module also withstands an operating shock of 10 g, making it suitable for vibration-prone environments.
Application Scenarios and Use Cases
This module excels in applications requiring individually isolated, high-current relay switching, such as motor starters, solenoid valves, and lighting controls. In a typical manufacturing line, the 1746-OX8 can manage multiple high-inrush loads while maintaining galvanic isolation between channels. Its wide operating voltage range also allows integration into both AC and DC control circuits without additional converters.
Compatibility and Integration
The 1746-OX8 is designed for the Allen-Bradley SLC 500 series and mounts directly into a compatible chassis. It communicates via the backplane, drawing 85-90 milliamps, and requires no special configuration beyond standard SLC 500 programming. For optimal performance, ensure the module is installed and removed only when power is removed from the chassis.
Market Impact and Business Value
By choosing the 1746-OX8, facilities can reduce downtime associated with relay failures and simplify maintenance with individually isolated outputs. Its robust construction and proven SLC 500 platform compatibility offer long-term reliability, lowering total cost of ownership. For engineers seeking a high-current relay output solution, this module provides a balance of performance and value.
