Description - SICAM MMU

SICAM MMU (Measurement and Monitoring Unit) is a power monitoring device that allows the measuring of electrical quantities in electrical networks in a single unit. In industries, power plants and substations, the SICAM MMU is applied to measure and calculate parameters (e.g. current, voltage, power, phase angle, harmonics and unbalance, energy or frequency) and assign them into further processing and visualization to control center (SCADA, DMS, EMS etc) through IEC 60870-5-104 or automation system over MODBUS TCP Protocols.

Features

• Design: Compact and robust for flexible application in industrial and utility environments??
• Connections in 1-phase systems, as well as in 3-wire and 4-wire systems
• Applications: Flexible for power utilities, industrial and commercial sector applications
• Measurements: more than 100 measured or calculated values available
• Temperature range: -25 °C to +55 °C/-13 °F to 131 °F
• Uncertainty: typically 0.1 % for voltage and current at rated input IEC 60688, and 0.2 s acc. to IEC 62053-21
• High EMC immunity: according to standards EN 61000-6-2 and EN 61000-6-4 for the EMC directives, and with the standard EN 61010-1 for the low-voltage directive
• UL Certfication: This product is UL-certified to standard UL 61010-1
• KEMA certification – IEC 60870-5-104 de.2 (IS2006)

Highlights

• Flexible current measurement range (up to 2 ? In)
• 2 individual binary outputs for fast switching, indications (e.g., limit violation) and operation status monitoring
• 4 LEDs for local status visualization
• Ethernet communications via IEC 60870-5-104 (if required redundantly executable) or MODBUS TCP protocols
• Internal battery for real time clock and saving of energy counter values in case of a power outage
• User-friendly operation through Web server (no extra software for parameterization needed, no converters and extra cables)
• Real time clock (RTC), field bus synchronization or networksynchronization possible via NTP
• ??Transmission of energy points via IEC 60870-5-104 protocoll???
• Extension of I / Os using the SICAM I / O Unit as sub-device via the Ethernet interface.
