Available factory installed accessories: A highly integrated 16-bit micro-controller uses digital signal processing techniques to analyze power system quantities and implement scheme logic. The micro-controller performs all of the major software functions such as input signal processing, scheme logic, output relay control and handling of the operator interface. The relay has 2 analogue inputs and 8 opto-isolated digital inputs. The internal VTs are used to isolate stepdown and condition the input from the line VTs. Their output signals are then converted into digital data for further processing. The front plate contains a 2 x 16 character, alphanumberic liquid crystal display (LCD) and 4 pushbuttons to provide local access to the relay’s menu. There are also 3 light emitting diodes (LED) for visual indication of the relay’s status. Standard Midos terminal blocks are located at the rear of the relay providing connections for all input and output circuits such as dc supply, ac voltage and a K-Bus communications port.
