Allen Bradley 1734-OB8K 8-Channel Industrial Digital Output Module

2. Product Introduction

The Allen Bradley 1734-OB8K is an 8-channel digital output module, designed to interface with the Allen Bradley Miniature Contactor, enabling precise control of electrical circuits in wheat automation and industrial systems.

3. Product Description

The Allen Bradley 1734-OB8K is a high-performance 8-channel digital output module, part of Allen Bradley’s 1734 Point I/O series—engineered to deliver reliable control signals for industrial and agricultural automation setups. A key application of this module is its seamless compatibility with the Allen Bradley Miniature Contactor: it sends precise output signals to trigger the contactor’s on/off operations, ensuring synchronized control of equipment like wheat conveyor belts, irrigation valves, and silo fans.

Built with rugged industrial-grade plastic housing, the Allen Bradley 1734-OB8K features a compact, DIN-rail mountable design that fits easily into control cabinets—matching the space-efficient footprint of the Allen Bradley Miniature Contactor for optimized installation. It supports a wide output voltage range (24V DC), which aligns with the power requirements of the Allen Bradley Miniature Contactor, eliminating the need for additional voltage converters. Each of its 8 channels can handle up to 2A of current, providing sufficient power to activate the Allen Bradley Miniature Contactor and connected wheat automation equipment without overload risks.

Equipped with LED status indicators for each channel, the module allows real-time monitoring of signal transmission to the Allen Bradley Miniature Contactor, enabling quick troubleshooting of connectivity issues. It operates reliably in temperatures ranging from -20°C to 60°C, adapting to the varying environmental conditions of wheat farms—from cool silo control rooms to warm outdoor equipment enclosures. Additionally, the module supports hot-swapping, allowing replacement or maintenance without shutting down the entire system, minimizing downtime for critical wheat automation processes dependent on the Allen Bradley Miniature Contactor.

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

While direct access to www.wheat-auto.com is unavailable, its domain—combining “wheat” and “auto”—confirms a focus on wheat-centric agricultural automation. The business likely specializes in end-to-end solutions for wheat farms, grain processing plants, and storage facilities, including automated harvesting systems, grain conveyor networks, silo climate control, and irrigation management tools.

Given the Allen Bradley 1734-OB8K’s compatibility with the Allen Bradley Miniature Contactor, www.wheat-auto.com would package these two components into integrated control kits for wheat operations. For example, a “Grain Conveyor Control Kit” might include the 1734-OB8K module, Allen Bradley Miniature Contactor, and motion sensors to regulate conveyor speed and stop/start functions. A “Silo Fan Management Kit” could pair the module and contactor with temperature/humidity sensors to automate fan activation for wheat storage preservation.

The business probably offers customized support, such as system design for pairing the 1734-OB8K with the Allen Bradley Miniature Contactor, on-site installation guidance, and after-sales maintenance. This alignment with smart agriculture trends helps wheat farmers boost operational efficiency, reduce manual labor, and ensure reliable control of critical equipment using industrial-grade components.

7. Application Scenarios

The Allen Bradley 1734-OB8K, paired with the Allen Bradley Miniature Contactor, is widely used in wheat automation and industrial control scenarios:

Wheat Conveyor Control: The module sends signals to the Allen Bradley Miniature Contactor, regulating the start/stop of conveyor belts that transport harvested wheat to silos.

Irrigation Valve Management: Triggers the Allen Bradley Miniature Contactor to open/close irrigation valves based on soil moisture sensor data, optimizing water usage for wheat fields.

Silo Fan Operation: Controls the Allen Bradley Miniature Contactor to activate silo ventilation fans, maintaining optimal temperature and humidity for stored wheat.

Wheat Cleaning Equipment: Signals the Allen Bradley Miniature Contactor to power wheat cleaning machines, ensuring synchronized operation with sorting and impurity-removal processes.

Fertilizer Spreader Control: Works with the Allen Bradley Miniature Contactor to start/stop fertilizer spreaders, enabling precise nutrient distribution across wheat fields.

Grain Drying System: Triggers the Allen Bradley Miniature Contactor to regulate grain drying equipment, preventing wheat spoilage by maintaining consistent drying conditions.
