DESCRIPTION

· The 3UG4501-1AA30 is an analog monitoring relay designed for fill level and resistance monitoring.

· It operates within a resistance range of 2 to 200 kohm and supports both overshoot and undershoot detection.

· The relay is powered by a 24 V AC/DC supply voltage at 50 to 60 Hz, without galvanic isolation to the measuring circuit.

· It offers 2-step or 1-step control with a tripping delay adjustable from 0.5 to 10 seconds.

· The device features a 1 change-over contact screw terminal and is the successor to the 3UG3501-1AC20 model.

FEATURES

· LED display for status indication.

· Apparent power consumption of maximum 2 VA at both DC and AC 24 V.

· Insulation voltage rated at 300 V for overvoltage category III with a degree of pollution 3.

· Surge voltage resistance rated at 4 kV, with a protection class of IP20.

· High mechanical and electrical endurance, with typical values of 10,000,000 and 100,000 operating cycles respectively.

· Relative repeat accuracy of 1%.

APPLICATIONS

· Suitable for monitoring liquid levels in tanks and containers.

· Ideal for resistance monitoring in industrial control systems.

· Can be used in environments requiring robust shock and vibration resistance.

· Applicable in systems where precise control and monitoring of electrical parameters are necessary.
