UMG 96L / UMG 96
Areas of application
• Replaces analogue measurement devices
• Display and checking of electrical characteristics in energy distribution systems
• Limit value monitoring
Main features
Display selection and automatic display rotation
• Generous LCD display
• All measured values can be called up in factory setting
• Measured values that are not required can be hidden and displayed again
Operating hours counter
• The operating hours counter is active as soon as the device is switched on
• The time is measured with a resolution of 15 minutes
• Display in hours mode
Digital outputs for reactive or active energy
• Transmission of the reactive and active energy via digital outputs
• The active energy should be assigned to output 1 and the reactive energy
to output 2

Digital outputs for threshold values (UMG 96)
• Digital outputs also suitable for use as switch outputs
• Programming the digital outputs for threshold monitoring of
measurement data
• Assignment of a measured value (threshold value) per switch output
• The associated output reacts in response to the value exceeding or
dropping below the threshold value
• Transistor outputs
Fig.: Digital output for threshold value monitoring
Password
• 3-digit password protects against unauthorised changing
of the programming and configurations
• Changes in the following program menus can only be implemented after
entering the correct user password
• Password is not factory-programmed
