Siemens Siprotec 5 6MD85 Bay Controller Protection Relay

The SIPROTEC 5 6MD85 Bay Controller Relay is a control and automation device with optional protection function. It is designed for use in all voltage levels from distribution to transmission. As a full member of the SIPROTEC 5 family, it allows the use of a large number of protection functions from the SIPROTEC library with identical parameters like in the protection devices.

The modular hardware enables the user to integrate as many IO’s as needed. Main function: Bay Controller for medium and high voltage switchgear. Integrated operator panel and key switches (optional). Powerful automation functionality, easily configurable with DIGSI. A large number of protection functions available. Inputs and outputs:-5 predefined standard variants with 4/4-current/voltage transformers,-11 to 75 binary inputs,-9 to 41 binary outputs Hardware flexibility: Flexible adjustable HW IO-quantity within the scope of the SIPROTEC5 modular system. The use of a second row allows more than 400 in- and outputs .Width of housing:1/3 x 19 Inch – 2/1 x 19 Inch

All 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.
