Power Quality Monitoring

▼Chapter 6Field bus componentsM-Bus signal converter PW60M-Bus installations are characterised by their simple cabling. Janitza electronics ® has madeaccommodations for this and has developed the UMG 96S with M-Bus interface.Using the signal process-controlled M-Bus level converter PW60, up to 60 x UMG 96S M-Buscan be connected to one PC (master). M-Bus software which is available on the market or theGridVis software can be used to analyse the data.Features: Integrated RS232 interface (PC as master) Galvanic separation between M-Bus and PC Baud rates: 300 to 9600 baud Bit recovery Protection against excess currents and short-circuits in the M-Bus Echo reduction and collision recognition with break signals Operational display, data transactions, maximum bus current and excess current External 24V DC or AC power supply is required Housing for DIN-C rails or wall mounting Dimensions (WxLxD) = 78 x 70 x 118mm Protection class: IP20 Maximum network dimension for JYSTY Nx2x0.8 = 1km (9600 baud) 4km (2400 baud) Maximum distance to slave for JYSTY Nx2x0.8 => 1200m Power consumption: 15W Operating voltage range: 20...45V DC or 20...30 V AC Operating temperature range: 0...+55°C Storage temperature: -20...60°C Item number: 15.06.048▼Application:Simple installationin GridVisGridVisLevel converterM-Bus to RS232UMG 96SM-BusUMG 96SM-BusUMG 96SM-BusM-BusM-BusM-BusIn GridVis, the following measurement parameters are available online with M-Bus:Effective energy, effective energy purchase (purchase or high tariff), effective energy (supply or low tariff), reactive energy, reactive energy(capacitive or high tariff), reactive energy (inductive or low tariff), apparent energy, comparator runtimes 1a to 2c, operating hoursmeter, current in N, effective power sum, reactive power sum, apparent power sum, UL1, UL2, UL3, IL1, IL2, IL3, PL1, PL2, PL3.Note: it is not possible to read the UMG 96S memory with the M-Bus. However, online recording can be activated in GridVis. Pleasenote that due to the low M-Bus baud rates in case many measuring instruments are used longer delays can occur.189
