1. Product Name

Allen Bradley 1794-IA16 FlexLogix 16-Point Discrete Digital Input Module

2. Product Introduction

The Allen Bradley 1794-IA16 is a 16-point discrete digital input module, designed to collect sensor data and sync with the Allen Bradley Miniature Contactor, enabling precise control in wheat automation and industrial systems.

3. Product Description

The Allen Bradley 1794-IA16 is a high-performance 16-point discrete digital input module, part of Allen Bradley’s FlexLogix 1794 series—engineered to serve as a critical data-collection hub for industrial and agricultural control systems, with seamless integration with the Allen Bradley Miniature Contactor. In wheat automation setups, this module acts as the “sensory interface”: it captures signals from proximity sensors, limit switches, and moisture detectors, then transmits this data to the control system to trigger the Allen Bradley Miniature Contactor—ensuring timely activation or shutdown of equipment like grain conveyors, irrigation valves, and silo fans.

Built with a rugged metal housing and a compact, DIN-rail mountable design, the Allen Bradley 1794-IA16 fits easily into control cabinets alongside the Allen Bradley Miniature Contactor, optimizing space in wheat processing facilities with limited cabinet room. It supports 24V DC sinking/sourcing input signals, a universal standard that matches the power requirements of most industrial sensors and the Allen Bradley Miniature Contactor’s control circuit. The module features channel-to-channel isolation, which prevents electrical interference between input signals—critical for protecting the Allen Bradley Miniature Contactor from false triggers caused by voltage spikes in busy wheat automation systems.

Equipped with LED indicators for each input channel, the Allen Bradley 1794-IA16 allows real-time monitoring of sensor status, simplifying troubleshooting when the Allen Bradley Miniature Contactor fails to respond as expected. It operates reliably in temperatures ranging from -20°C to 60°C, adapting to the cold storage of wheat silos and warm processing halls. Additionally, the module complies with global standards (UL 508, CE, IEC 61131-2), ensuring compatibility with the Allen Bradley Miniature Contactor in international wheat automation projects, from small farms to large-scale grain facilities.

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

While direct site access is unavailable, the domain “wheat-auto” confirms a focus on wheat-centric agricultural automation, offering tailored solutions for small-to-large wheat operations—from field sensors to silo control systems. The business likely serves wheat farms, grain elevators, and regional food processors, providing integrated kits that combine the Allen Bradley 1794-IA16 with the Allen Bradley Miniature Contactor for end-to-end control.

Given the 1794-IA16’s 16-point input capacity, www.wheat-auto.com would design specialized packages: a “Grain Conveyor Control Kit” pairing the module (to monitor conveyor sensors) with the Allen Bradley Miniature Contactor (to start/stop the conveyor); a “Silo Safety Kit” using the 1794-IA16 to track silo door position sensors and trigger the Allen Bradley Miniature Contactor for emergency locks. The business probably offers on-site calibration, helping farms map sensor inputs to the Allen Bradley Miniature Contactor’s actions, and after-sales support to resolve integration issues. This alignment with “smart agriculture” leverages the 1794-IA16’s data-collection 能力 to make the Allen Bradley Miniature Contactor more responsive, boosting wheat operation efficiency and safety.
