1. Product Name
Allen Bradley 109-C12AD-OLR-1-901 Overload-Protected Miniature Contactor for Wheat Farm DC Motors
2. Product Introduction
The Allen Bradley 109-C12AD-OLR-1-901 is an overload-protected Allen Bradley Miniature Contactor, designed for safe control of DC motors in wheat farm equipment like irrigation pumps and seeders, preventing burnout from debris or jams.
3. Product Description
The Allen Bradley 109-C12AD-OLR-1-901 is a safety-focused Allen Bradley Miniature Contactor, part of Allen Bradley’s 109 series engineered to address overload risks in wheat farm DC motor operations. Unlike standard contactors, this Allen Bradley Miniature Contactor integrates a built-in overload relay (OLR), automatically cutting power to DC motors when current exceeds safe limits—preventing motor burnout from grain dust clogs or mechanical jams common in farm equipment.
Optimized for wheat farm DC systems, it features a 24V DC coil, perfectly matching solar-powered or portable low-voltage setups without needing AC-DC converters. The Allen Bradley Miniature Contactor handles 12A rated current, supporting small-to-medium DC motors (up to 3HP) used in irrigation pumps, electric seeders, and grain conveyors. Its housing has a dust-resistant coating to repel wheat chaff and field dust, while compact dimensions (81×53×47mm) fit narrow control cabinets of mobile farm machinery. Tool-less push-in terminals reduce on-site installation to under 15 minutes, critical during busy planting/harvest seasons.
Compliant with IEC 60947-4-1 and UL 508 standards, this Allen Bradley Miniature Contactor ensures reliable performance in harsh farm conditions. It boasts a mechanical service life of 4.5 million operations and electrical life of 500,000 operations—covering over 4 wheat growing cycles. The DC coil also cuts power consumption by 30% vs. AC equivalents, aligning with farms’ solar energy goals.

5. Product Advantages

  • Built-In Overload Protection: OLR stops DC motor burnout from dust clogs/jams, boosting wheat farm equipment reliability.

  • DC System Compatibility: 24V DC coil works with solar/portable farm setups, no AC-DC converters needed.

  • Dust-Resistant Design: Coated housing repels wheat chaff and field dust, reducing malfunctions.

  • Rapid Installation: Tool-less terminals cut setup time to <15 minutes, fitting tight farm schedules.

  • Energy Efficiency: DC coil uses 30% less power than AC contactors, ideal for solar-powered wheat farms.

  • Long Service Life: 4.5M mechanical operations cover 4+ wheat cycles, lowering replacement costs.

6. Business Insight on www.wheat-auto.com
While direct site access is unavailable, the domain “wheat-auto” confirms its focus on wheat-centric agricultural automation, serving wheat farms, grain cooperatives, and small flour mills. This Allen Bradley Miniature Contactor (109-C12AD-OLR-1-901) would be a staple in the site’s “DC motor safety kits” for wheat equipment.
The site likely packages it into solutions like “solar irrigation pump safety bundles” (leveraging OLR and DC compatibility) or “electric seeder protection kits” (using dust resistance). It may offer farm-specific resources: OLR current setting guides for wheat motors, dust-coating maintenance tips, and solar system compatibility charts. By emphasizing the contactor’s ability to solve motor burnout— a top wheat farm pain point—www.wheat-auto.com positions itself as a provider of durable, safety-focused automation tools. This aligns with its mission to reduce downtime during critical growing seasons, using industrial-grade components like the Allen Bradley Miniature Contactor.
7. Application Scenarios
The Allen Bradley 109-C12AD-OLR-1-901, as an overload-protected Allen Bradley Miniature Contactor, excels in wheat farm DC motor control:

  • Solar DC Irrigation Pumps: OLR protects pumps from grain debris clogs, while DC compatibility matches solar power.

  • Electric Wheat Seeders: Overload relay prevents motor burnout from jammed seed tubes, compact design fitting seeder cabinets.

  • DC Grain Conveyors: Stops conveyor motors from overheating due to dust buildup, ensuring smooth grain transport.

  • Portable DC Sprayers: OLR safeguards sprayer motors from clogging, low power use extending battery life in fields.

  • DC Grain Dryer Fans: Prevents auxiliary fan burnout from wheat chaff, dust resistance handling dryer dust.

  • Wheat Feed Mixers: Overload protection stops mixer motors from jamming with wheat-based feed, DC coil 适配 (adapting to) low-voltage supplies.
