Main features of the UMG 96RM-E

COMPACT, RELIABLE & MULTIFUNCTIONAL

The UMG 96RM-E measures harmonics up to the 40th harmonic and has a measurement data memory with 256 MB. The multifunctional network analyzer has two digital outputs and three digital inputs and outputs that can be defined as required.

MEMORY

Many UMG measurement devices have their own memory with typical recording ranges of up to 2 years. Recording is freely configurable. A 128 MByte memory can store around 5,000,000 memory values, a 256 MByte memory can store around 10,000,000 memory values.

ALARM MANAGEMENT

The GridVis® alarm management system monitors all measurement parameters obtained by the UMG measurement devices. It includes escalation management, logbook function and user administration for individual notifications by e-mail, pop-up window on the monitor, etc.

DIFFERENTIAL CURRENT (RCM)

A conductive RCM residual current monitor detects fault currents at an early stage, before they lead to system failures or even fires. Continuous RCM monitoring significantly increases system safety and availability.

MEASURING DEVICES-HOMEPAGE

The web server on the measuring device provides a wide range of data in a clearly structured form. The user does not need to install any software on his PC, a standard web browser is sufficient.

ETHERNET-MODBUS-GATEWAY

Modbus RTU devices that are connected to the master device as slaves can be very easily integrated into an Ethernet architecture via the Ethernet Modbus gateway. For devices with an identical file format and matching function codes, this is possible directly via the Modbus RTU interface.

BACNET

BACnet is one of the most important communication standards for building technology, primarily due to its compatibility with a wide variety of hardware and its standardized, manufacturer-independent communication. As soon as a UMG measurement device has received its BACnet ID and is integrated into the network, it is recognized by the system and displayed in the browser.
