JTK50-15/B Irrigation RF Card Controller – Intelligent, Reliable, and Easy-to-Use Field Control

Shandong Jintian‘s JTK50-15/B Irrigation RF Card Controller is a core component of modern agricultural well irrigation systems. This controller integrates advanced microcomputer processing, radio frequency triggering, high-performance integrated circuit technology, and automatic control into a single, durable unit-. Designed for seamless installation in pump houses, glass fiber reinforced plastic (GFRP) well rooms, or distribution cabinets-, it enables precise, prepaid management of water and electricity usage for farming operations.

Key Features & Benefits

• RF Card Technology – Utilizes contactless RFID (13.56MHz, compliant with ISO/IEC14443A) for secure, wireless reading and writing of card information. Features waterproof, moisture-proof, and tamper-resistant construction-. Card data can be preserved for over 10 years and supports more than 100,000 read/write cycles.

• Flexible Metering Options – Supports billing by electricity (accurate to 0.1 kWh), water volume (accurate to 1 ton), or irrigation time (accurate to 1 second)-. The system can be configured to meet local water pricing and management requirements.

• Prepaid & Auto-Shutoff – Operates on a prepaid basis with one controller supporting multiple user cards-. When the card balance is depleted, the controller automatically stops the pump, preventing unauthorized usage.

• Low Balance Alert – Automatically triggers an audible or visual warning when the card balance falls below a preset threshold, prompting users to recharge in time-.

• Simple On-Field Operation – Users simply tap their RF card on the controller to start the pump and tap again to stop-. The system automatically deducts the appropriate fee from the card upon completion of irrigation-.

• Wide Operating Range – Reliable performance in temperatures from -30°C to +70°C, suitable for diverse climatic conditions.

• Built-in Protections – Includes overload, short-circuit, and phase-loss protection to safeguard both the controller and connected pump equipment.

• Rich Interface Options – Equipped with RS-232/RS-485 digital signal interfaces for connectivity with water meters, electricity meters, and other field sensors. Supports analog signal (AI), pulse, and switching signal (PI/DI) inputs-.

• Data Security – Controller data can be stored for up to 10 years-. Village code binding prevents cross-village card misuse, ensuring localized and secure management.
