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

While direct access to www.wheat-auto.com is unavailable, the domain “wheat-auto” confirms a focus on wheat-centric agricultural automation, offering end-to-end solutions from outdoor wheat farming equipment (e.g., harvesters, irrigation systems) to indoor grain processing and storage setups (e.g., silos, flour mills). The business likely serves commercial wheat farms, large grain elevators, and regional food processing plants, providing customized automation packages that include control panels, sensors, and safety components.

Given the Allen Bradley 1492-SPM1B250’s role in protecting Allen Bradley Miniature Contactor, www.wheat-auto.com would integrate this module into critical wheat equipment: wheat irrigation pump control panels (protecting contactors from overloads during peak watering seasons), grain conveyor motor cabinets (safeguarding contactors from current spikes when moving heavy grain loads), and wheat harvester engine auxiliary systems (shielding contactors from overloads in variable field conditions). It would leverage the module’s IEC/UL compliance to meet agricultural safety standards (e.g., ISO 23387 for grain handling equipment) and offer “contactor + protection module + installation support” bundles to simplify setup for farms with limited technical expertise. Additionally, the business probably provides on-site maintenance services— such as module calibration and contactor inspection— addressing rural operational challenges, positioning itself as a trusted provider of reliable, safety-focused agricultural automation solutions.

7. Application Scenarios

The Allen Bradley 1492-SPM1B250 is essential for protecting Allen Bradley Miniature Contactor in agri-industrial environments:

Wheat Farm Irrigation Pumps: Installed with Allen Bradley Miniature Contactor in pump control panels, adjusts to 5-15A trip settings to prevent overloads during peak watering.

Grain Silo Fan Systems: Paired with the contactor in fan control boxes, 2-8A settings protect against current spikes when fans start under heavy dust loads.

Wheat Harvester Auxiliary Motors: Integrated with the contactor in harvester control enclosures, -25°C resilience ensures protection in cold early-morning harvesting.

Industrial Conveyor Belts (Grain Processing): Used with the contactor in conveyor motor cabinets, fast trip response prevents damage from grain jams.

Flour Mill Mixer Controls: Paired with Allen Bradley Miniature Contactor in mixer panels, 10-20A settings handle variable load during dough mixing.

Cold Grain Storage Heaters: Integrated with the contactor in heater control systems, 1-5A settings protect against overloads in frozen storage facilities.
