Siemens 3UG48152AA40

The Siemens 3UG48152AA40 is a digital monitoring relay designed for three-phase supply voltage systems, perfectly suited for integration with IO-Link communication. This device reliably monitors voltages ranging from 160 to 690 V AC at frequencies between 50 and 60 Hz, ensuring stable operation by detecting phase sequence, phase failure, and phase asymmetry. It also provides protection against undervoltage and overvoltage conditions, with adjustable hysteresis from 1 to 20 volts. The relay includes configurable line stabilization and tripping delays to prevent nuisance trips, and it features a single change-over contact for switching purposes. Distributed by BSP Automation, this monitoring relay is a dependable choice for maintaining the integrity of industrial power supplies.
