Overview
SIRIUS 3UG4832 monitoring relays
The relays monitor single-phase AC voltages (rms value) and
DC voltages against the set limit value for overshoot and under-
shoot.
■
Benefits
•
Variably adjustable to overshoot, undershoot or range
monitoring
•
Freely configurable delay times and RESET response
•
Width 22.5 mm
•
Display and transmission of actual value and status messages
to controller
•
All versions with removable terminals
•
All versions with screw or spring-type terminals
■
Application
•
Protection of a plant against destruction due to overvoltage
•
Switch-on of a plant at a defined voltage and higher
•
Protection from undervoltage due to overloaded control
supply voltages, particularly with battery power
■
Selection and ordering data
•
Adjustable via IO-Link and locally, with illuminated LCD
•
Power supply with 24 V DC via IO-Link or external auxiliary
voltage
•
Auto or Manual RESET
•
Open or closed-circuit principle
•
