Description
The DISIBEINT PNFA 400 100 is a robust Level and Phase Failure Control Relay, designed for industrial applications that require simultaneous liquid level control and phase failure monitoring. Manufactured by DISIBEINT and distributed by MES – Middle East Switchgear Ind. Ltd., this relay operates at 3 x 400 VAC and offers a sensitivity range of 10 to 100 KΩ.
- Level Control: This relay offers maximum and minimum level control for conductive liquids. It activates when the liquid reaches the electrode and releases when it falls below, ensuring precise liquid level management.
- Phase Failure Control: Simultaneously monitors phase failures, releasing the relay when a single-phase failure occurs at -20% of nominal voltage, and releasing fully at -15% during a three-phase failure.
- SPDT Output: Equipped with a Single Pole Double Throw (SPDT) output, the relay ensures flexibility in switching applications.
- Adjustable Sensitivity: The adjustable sensitivity from 10 to 100 KΩ allows for precise control based on liquid resistivity, ensuring reliability across different industrial processes.
- LED Indicators: Features green (power on) and red (relay on) LEDs for easy monitoring of operational status.
- Electrical Ratings: The relay supports 8 A at 250 V for resistive loads and 2.5 A at 250 V for inductive loads, ensuring reliable performance in diverse industrial environments.
- Durability: Built for long-lasting use with over 30 million mechanical and 360 electrical operations per hour, ensuring durability in demanding settings.
- Environmental Protection: Rated IP 20, with an operating temperature range from -20°C to +50°C, making it suitable for tough industrial conditions.
- Certifications: Compliant with EEC standards for electromagnetic compatibility and electrical safety, providing reliable operation in regulated environments.
The PNFA 400 100 is ideal for industrial settings that require precise level control and reliable phase failure monitoring, ensuring operational safety and efficiency.
