SIPROTEC 6MD85

• Safe and reliable automation and control of your systems

• Purposeful and easy handling of devices and software thanks to a user-friendly design

• Cyber security in accordance with NERC CIP and BDEW White- paper requirements

• Highest availability even under extreme environmental conditions by “conformal coating“ of electronic boards

• Powerful communication components warrant safe and effective solutions

• High investment security and low operating costs due to future-oriented system solutions

DIGSI 5 permits all functions to be configured and combined as required.

• Integrated bay controller with versatile protection function from medium to extra-high voltage

• Control of switching devices

• Synchrocheck and switchgear interlocking protection

• Integrated electrical Ethernet RJ45 for DIGSI 5 and IEC 61850 (reporting and GOOSE)

• Up to 4 pluggable communication modules, usable for different and redundant protocols (IEC 61850,
  IEC 60870-5-103, IEC 60870-5-104, Modbus TCP, DNP3 serial and TCP, PROFINET IO)

• Reliable data transmission via PRP and HSR redundancy protocols

• Arc protection

• Extensive cyber security functionality, such as role-based access control (RBAC), protocolling security-related events
  or signed firmware

• Simple, quick and secure access to device data via a standard Web browser – without additional software

• Graphical logic editor to create powerful automation functions in the device

• Optional overcurrent protection for all voltage levels with 3- pole tripping

• Also used in switchgear with breaker-and-a-half layout

• Selective protection of overhead lines and cables with single- ended and multi-ended feeders using protection communication

• Overcurrent protection also configurable as emergency mode

• Secure serial protection data communication, also over great distances and all available physical media (optical fiber, two-wire connections and communication networks)

• Capturing operational measured variables and protection function measured values for the evaluation of the systems,
  to support commissioning, and to analyze faults

• Synchrophasor measured values with the IEEE C37.118 protocol Phasor Measurment Unit (PMU)

• Powerful fault recording (buffer for a max. record time of 80 sec. at 8 kHz or  320  sec. at 2 kHz)

• Auxiliary functions for simple tests and commissioning

• Flexibly adjustable I/O quantity structure within the scope of the SIPROTEC 5 modular system

The SIPROTEC 6MD85 bay controller is a general-purpose control and automation device with a protection function on the basis of the SIPROTEC 5 system. The standard variants of the SIPROTEC 6MD85 device are delivered with instrument
transformers. Furthermore, protection-class current transformers are also possible in SIPROTEC 6MD85 devices, allowing protection functions to be used. Due to its high flexibility, it is suitable as selective protection equipment for overhead lines and cables with single-ended and multi-ended infeeds when protection communication is used. The device supports all SIPROTEC 5 system characteristics. It enables upgradeable system solutions with high investment security and low operating costs.
