Characteristics

General Properties
• Powerful 32-bit microprocessor system
• Complete digital processing and control of measured value, from the sampling and digitalization of the mea-
sured quantities to close and trip decisions for the switchgear component
• Complete galvanic and interference-free isolation of the internal processing circuits of the measurement,
control and supply circuits of the system using instrument transformers, binary input and output modules,
and DC and AC voltage converters
• Easy device operation using the Web Monitor or a connected PC running DIGSI
• Continuous calculation and displaying of measured values and count values
• Continuous monitoring of the measured quantities and of the device hardware and software
• Communication with protection device and data storage equipment
• Battery-buffered clock which can be synchronized via a synchronization signal via GPS, IRIG-B or SNTP
(Simple Network Time Protocol) via Ethernet interface
• Operating hours counter: Counting the operating hours of the protected object under load
• Commissioning aids such as connection and direction check, status indication of all binary inputs and out-
puts, easy testing of port F, and influencing of information at port F during test operation
• Replacement of conventional wiring between primary and secondary devices through optical cables
• Support point to point. Using of redundant network technology (PRP, HSR)
• Use of proven SIPROTEC / DIGSI4 technology
• Easy installation and configuration supported by DIGSI and Syscon (System Configurator) via USB interface
Special Properties of Merging Unit
• Acquisition of 4 currents (1 A, 5 A) and 4 voltages (100 V, 110 V) of conventional current and voltage instru-
ment transformers of power system data
