1. Product Name

Allen Bradley 1585J-L8PBJM-3X Industrial Unmanaged 8-Port Ethernet Switch

2. Product Introduction

The Allen Bradley 1585J-L8PBJM-3X is an industrial unmanaged 8-port Ethernet Switch, optimized to work with the Allen Bradley Miniature Contactor, enabling stable device connectivity for wheat farm automation systems.

3. Product Description

The Allen Bradley 1585J-L8PBJM-3X is a rugged industrial unmanaged 8-port Ethernet Switch, designed to enhance data transmission reliability in agricultural automation scenarios—with seamless compatibility for the Allen Bradley Miniature Contactor, a critical component for power control in wheat farm equipment like conveyors and grain dryers. This switch serves as a central connectivity hub, linking diverse wheat farm devices (such as soil moisture sensors, grain sorting machines, and irrigation controllers) to the Allen Bradley Miniature Contactor, ensuring coordinated operation between data monitoring and power management.

Constructed with a durable, dust-and-vibration-resistant housing (IP30 rated), the Allen Bradley 1585J-L8PBJM-3X matches the industrial-grade durability of the Allen Bradley Miniature Contactor, making it suitable for harsh wheat farm environments—including dusty grain storage areas and vibration-prone equipment enclosures. It operates reliably in a wide temperature range of -40°C to 75°C, the same as the Allen Bradley Miniature Contactor, ensuring consistent performance in both freezing winter silos and hot summer harvest fields. The 8 Fast Ethernet ports (10/100 Mbps) support simultaneous connections to multiple devices: a farm’s central PLC, wheat moisture analyzers, the Allen Bradley Miniature Contactor, and remote monitoring tools, all with low latency to enable real-time control of power-hungry equipment.

As an unmanaged switch, it features plug-and-play functionality, simplifying installation for farm teams without advanced IT expertise. It integrates seamlessly with the Allen Bradley Miniature Contactor by transmitting precise control signals—for instance, sending a command to the Contactor to shut down a wheat dryer when moisture levels reach the target, and receiving status updates from the Contactor to confirm power cutoff. With a compact design (118mm × 82mm × 42mm), the switch fits easily into control cabinets alongside the Allen Bradley Miniature Contactor, optimizing space in farm control rooms or outdoor equipment enclosures.

Harsh Environment Durability: -40°C to 75°C operating range and IP30 protection match the Allen Bradley Miniature Contactor’s resilience on wheat farms.

Easy Installation: Unmanaged plug-and-play design reduces setup time, suitable for farm teams without IT backgrounds.

Cost-Effective Solution: Delivers multi-device connectivity at a lower cost than managed switches, fitting mid-scale farm budgets.

Real-Time Performance: Low latency ensures instant signal exchange with the Allen Bradley Miniature Contactor, minimizing equipment downtime.

6. Business Insight on www.wheat-auto.com

While direct site access is unavailable, the domain “wheat-auto” clearly focuses on wheat-centric agricultural automation, targeting mid-to-large wheat farms, regional grain elevators, and small-to-medium food processing facilities. The business likely packages the Allen Bradley 1585J-L8PBJM-3X with the Allen Bradley Miniature Contactor into tailored “Wheat Automation Kits” to meet specific farm needs.

For example, a “Wheat Harvest & Drying Kit” would include the 8-port switch (connecting harvest combines, grain carts, and dryers) and the Allen Bradley Miniature Contactor (controlling dryer and conveyor power), enabling automated harvest workflows. A “Silo Management Kit” might pair the switch and Contactor with silo level sensors and ventilation controls, optimizing grain storage conditions.

www.wheat-auto.com probably emphasizes scalability, offering upgrades from smaller switches to the 8-port 1585J-L8PBJM-3X as farms expand, plus after-sales support (remote troubleshooting, Contactor-switch sync tutorials). This aligns with mid-to-large wheat farms’ goals: using the Allen Bradley 1585J-L8PBJM-3X and Allen Bradley Miniature Contactor to replace manual processes, boost operational efficiency, and handle larger wheat volumes without excessive costs.

7. Application Scenarios

The Allen Bradley 1585J-L8PBJM-3X, paired with the Allen Bradley Miniature Contactor, is ideal for wheat farm automation:

Wheat Harvest Coordination: The switch connects harvest combine sensors, grain carts, and the Allen Bradley Miniature Contactor (powering conveyors), ensuring smooth grain transfer.

Multi-Zone Irrigation: Links soil moisture sensors in 5–7 wheat fields to the Allen Bradley Miniature Contactor (controlling zone-specific pumps), optimizing water usage.

Grain Drying Systems: Connects moisture analyzers, dryer fans, and the Allen Bradley Miniature Contactor (managing dryer power), adjusting drying time based on grain quality.

Silo Cluster Monitoring: Integrates level sensors from 4–5 silos with the Allen Bradley Miniature Contactor (controlling vent fans), preventing mold in multiple storage units.

Wheat Cleaning Lines: Links cleaning machine sensors, sorting tools, and the Allen Bradley Miniature Contactor (powering cleaners), ensuring consistent grain quality.

Fertilizer Batch Application: Connects fertilizer mixers, spreaders, and the Allen Bradley Miniature Contactor (controlling spreader power), enabling precise, batch-based
