A scalable range of integrable, multifunctional power meters are available as plug-in modules for the Bachmann automation system. The measurement of all characteristic grid variables such as voltage, current, power or frequency directly within the control system allows significant correlation with other operational data, as well as an excellent reaction time. The measured data is rapidly calculated without additional delays due to fieldbusses or transceivers.
Each module type integrates with the entire M200 IO portfolio and can be used multiple times per CPU. The PLC’s SSL/TLS secured authentication and authorization unit protects the grid measurement modules from unwanted changes and cyberattacks. All types of field busses, including SAE J1939 as well as OPC UA and RTU standards such as IEC 61850, IEC 60870-5-101/-103/-104, DNP3 or Modbus, are available to exchange data with network operators, plant controllers or generation units.
Existing type approvals for generation units according to VDE-AR-N 4105/4110, ENA ER G99 and IEEE Std. C37.90 simplify the operational notification and compliance process. Maritime Class Approvals from DNV, BV, LR, ABS, RINA, KR and NK allow implementation on vessels and offshore installations. Compliance with UL/cUL and CSA make the units suitable for applications in North America.
A coated version allows grid measurement and protection even in challenging environments with high humidity, from tropical heat to cold starts in polar regions.
