HRH-5
Level Control Relay
The ELKO EP HRH-5 Level Control Relay is designed for precise monitoring of conductive liquid levels in wells, tanks, or reservoirs using external probes (not included). This versatile device can be configured for either one-level or two-level switching operations, making it suitable for a variety of applications. The relay features adjustable sensitivity ranging from 5 to 100 kΩ and an adjustable output time delay from 0.5 to 10 seconds, allowing for tailored performance to meet specific needs.With a wide universal supply voltage range of 24-240V AC/DC, the HRH-5 ensures compatibility with various power systems. The device is equipped with a single changeover contact rated at 8A/250V AC1, providing reliable switching capabilities. The measuring frequency of 10 Hz prevents polarization of the liquid and reduces oxidation of the measuring probes, ensuring long-term accuracy and reliability.Installation is straightforward with DIN rail mounting, and the device includes galvanically separated supply voltage for enhanced safety. The HRH-5 complies with relevant industry standards, ensuring dependable performance in demanding environments. It is ideal for applications such as pump control in water treatment facilities, irrigation systems, and industrial fluid management.
