Addressing Output Challenges in Industrial Automation
Industrial control systems often face the challenge of reliably switching AC loads in harsh environments. Engineers need output modules that can handle varying voltages and currents without compromising performance. The Allen-Bradley 1746-OA8 provides a robust solution for these demanding applications.
Introducing the 1746-OA8 from Petro Auto Tech
Petro Auto Tech now offers the Allen-Bradley 1746-OA8, a discrete AC output module from the SLC 500 series. This module features eight output channels arranged in two groups of four channels each. It is designed for general-purpose applications requiring reliable AC switching.
Technical Specifications Overview
The 1746-OA8 delivers an output voltage range of 85-264VAC with a frequency of 47-63 Hz. It consumes 185 mA of backplane current at 5VDC. Each output point can handle 1.00 A continuously at 30 °C, derating to 0.5 A at 60 °C. The total module current is 8.0 A at 30 °C and 4.0 A at 60 °C.
Application Scenarios and Use Cases
In manufacturing plants, the 1746-OA8 can control AC-powered actuators, solenoids, and motor starters. It is also suitable for packaging machinery where multiple AC loads need coordinated switching. The module's two isolated groups allow for separate power feeds or mixed voltage applications.
Customer Case Scenario
A food processing facility needed to upgrade its conveyor control system. By integrating the 1746-OA8, the plant achieved reliable switching of eight AC motors while reducing wiring complexity. The module's derating curve allowed operation in the warm production environment without overheating.
Compatibility and Integration
The 1746-OA8 is designed for the Allen-Bradley SLC 500 programmable logic controller platform. It plugs directly into the SLC 500 chassis and communicates via the backplane. No additional communication modules are required for basic operation.
