AFR-1 Level Relay

The ‌AFR-1 Level Relay‌ is a robust, high-precision liquid level control device designed for industrial automation, water management, and HVAC systems. Utilizing advanced electrode-sensing technology, it ensures accurate detection of conductive liquids in tanks, sumps, or reservoirs up to 15 meters deep. The relay features adjustable sensitivity and hysteresis settings to minimize false alarms and optimize response to fluctuating fluid levels.

Housed in an IP65-rated enclosure, it withstands harsh environments, including exposure to dust, moisture, and temperatures ranging from -30°C to +70°C. Compatible with 12-240V AC/DC power supplies, its SPDT contacts (8A @ 250V AC) enable seamless integration into control panels for pump activation, alarm systems, or automated shutoff. Enhanced with LED status indicators and a manual override function, the AFR-1 simplifies troubleshooting and maintenance.

Compliant with IEC 60947-5-1 standards, this DIN-rail mountable relay is ideal for wastewater treatment, agricultural irrigation, and chemical processing, offering reliable protection against dry-running pumps or overflow conditions. Compact, durable, and maintenance-free, it ensures long-term operational efficiency and system safety.
