Siemens 3UG4501-1AA30 Analog Monitoring Relay (Phase-Out)
Siemens 3UG4501-1AA30 analog monitoring relay for level/resistance.
The Siemens 3UG4501-1AA30 is an analog monitoring relay designed for level and resistance monitoring, with features for detecting overshoot and undershoot. It operates on 24V AC/DC with a supply frequency of 50 to 60 Hz and includes a tripping delay adjustable from 0.5 to 10 seconds. This model is in phase-out, with the preferred successor being the 3UG5501-1AW30.
This relay is essential for applications such as liquid level control in tanks, monitoring resistance in heating elements, or ensuring process variables remain within set thresholds. It is widely used in water treatment, industrial process control, and machinery automation.
