Analogue monitoring relay Fill level monitoring Resistance monitoring from 2 to 200 kOhm Overshoot and undershoot AC/DC 24 to 240 V DC and AC 50 to 60Hz 2 point or 1 point control Tripping delay 0.5 to 10 s 1 changeover contact Screw connection Successor product for 3UG3501 Analogue adjustable fill level monitoring relay SIRIUS 3UG4 for monitoring the fill level of conductive liquids to protect against overflow, dry running or leakage. Worldwide use thanks to wide voltage supply and international certificates. Device replacement possible without rewiring thanks to removable terminals. Can be flexibly adapted to different conductive liquids thanks to analogue setting of the sensitivity. Inflow or outflow function can be selected. The adjustable tripping delay time can also compensate for wave movements. Other resistance sensors can also be connected, e.g. B. suitable photoresistors, temperature sensors, resistance-based position sensors, etc. In addition to screw connection technology, the devices are also available with spring-loaded connections for quick, maintenance-free and vibration-proof connections. Accessories include individually shortenable 2- and 3-pole wire electrodes for easy installation from above/below, as well as bracket electrodes for installation from the side for larger filling heights and minimal space requirements. Other accessories, such as device identification plates, push-in tabs and cover caps, are standard for all relays. SIRIUS relays - a program for all cases.
