Siemens Siprotec 5 7VK87 Circuit Breaker Management Device

SIPROTEC 7VK87 Circuit Breaker Management device  is part of the new SIPROTEC 5 series of modular, flexible and intelligent digital field devices. With its modularity and flexibility and its high-performance DIGSI 5 engineering tool, the SIPROTEC 7VK87 fits perfectly for protection, control, monitoring, and measuring applications in electrical energy systems. Main function: Automatic reclosing, synchro check, circuit-breaker failure protectionTripping-1- and 3-pole or 3-poleInputs and outputs:-12 predefined standard variants with 4/4 or 8/8 current/voltage transformers,-5 to 31 binary inputs,-4 voltage transformers-8 to 46 binary outputs Hardware flexibility: Flexibly adjustable I/O quantity structure within the scope of the SIPROTEC 5 modular system Width of housing:1/3 x 19” to 2/1 x 19”

Alll functions can be configured freely with DIGSI 5. For the application of some of the functions, you require the appropriate number of free function points within the device. The function point calculator in the online configurator provides support in determining the required number of function points for your device.
