Siemens 3UG5501-1AW30 relé analógico de control de nivel, conductivo, 1 canal, AC/DC 24-240 V, 2 conmutadores

Analog level monitoring relay with conductive measuring principle for precise liquid level control. Monitors one channel with adjustable resistance range from 0.2 kOhm to 200 kOhm, making it ideal for conductive liquids. Wide supply voltage range AC/DC 24-240 V ensures compatibility with various control systems.

Advantages

Reliable conductive level detection with adjustable hysteresis (5-50%) prevents relay chatter. Response and startup delays (0.1-20 s) allow customization for process stability. Two change-over contacts provide flexible output switching. DIN rail mounting and screw terminals enable quick installation. IP20/IP40 protection suits industrial control cabinets.
