Products - ME 4012 PA-F Field Unit
Universal Field Unit for the Use in High-Voltage and Extra-High-Voltage Switchgears
The automation technology for energy supply and distribution plants is rapidly advancing. New communication techniques and devices and standard protocol interfaces combined with the immense computing power of today’s hardware components open the way to new concepts in distributed station automation. At the same time, the growing demands of utility owners for more cost-effective station control systems must be met.
ME 4012 PA-F is our solution for all aspects of distributed station automation in high-voltage and extra-high-voltage applications.
Whether as field unit or as switchgear interlock unit, due to its modular design the ME 4012 PA-F easily adapts to the specific task and the quantity of data to be processed.
IEC 60870-5 based information processing allows the assignment of quality characteristics to the process data items right at the source, which is a precondition for direct or indirect connection to existing or future network control systems.
The system’s input and output modules are designed for the direct connection of binary signals of up to 220 V DC, the acquisition of secondary variables of current and voltage transformers (1 A, 2 A, 5 A or 100 V), as well as for the direct control of switching devices.
It is also possible to directly connect digital protection equipment using the system’s two IEC 60870-5-103 interfaces.
