Siemens - 3UG4501-1AW30 ANALOG MONITORING RELAY FILL LEVEL MONITORING RESISTANCE MONITORING FROM 2 TO 200 KOHM 0VERSHOOT AND UNDERSHOOT 24 TO 240 V AC/DC 50 TO 60 HZ DC AND AC 2-STEP OR 1-STEP CONTROL TRIPPING DELAY 0.5 TO 10 S 1 CHANGE-OVER CONTACT SCREW TERMINAL SUCCES

Analog monitoring relay Fill level monitoring Resistance monitoring from 2 to 200 kohm 0vershoot and undershoot 24 to 240 V AC/DC 50 to 60 Hz DC and AC 2-step or 1-step control Tripping delay 0.5 to 10 s 1 change-over contact screw terminal Successor product for 3UG3501 Level monitoring relay with analog setting SIRIUS 3UG4 for level monitoring of conductive fluids to protect against overflow, dry running or leakage.Worldwide use thanks to wide voltage supply range and international certificates. Device replacement possible without rewiring, thanks to removable terminals Can be flexibly adapted to various conductive liquids through analog setting of the sensitivity. Upstream or downstream function is selectable By means of the adjustable tripping delay time, it is also possible to compensate for shaft movements. Other resistance sensors can also be connected, e.g. suitable photoresistors, temperature sensors, position encoders based on resistors etc.In addition to screw terminals, all the devices are also available with spring-type terminals for fast, maintenance-free and vibration-proof connection.Available accessories include individually shortenable two-pole and 3-pole wire electrodes for easy mounting from above/below, as well as bow electrodes for installation from the side to allow higher filling levels and minimal space requirements. Additional accessories, such as unit labeling plates, push-in lugs and cover caps, are standardized for all relays.SIRIUS relays - one range for every application.
