主系统c.t和v.t直接连接到216GW61输入变压器单元。测量的信号
输入变量被逐步降低到适当的水平，以供电子电路（模拟信号）处理并传输通过系统电缆连接到216EA61单元，该单元将其数字化并将其发送到B448C并行总线。处理单元连续比较从主要系统量导出的数字化测量变量216VC62a，具有保护功能的拾取设置。如果保护功能启动，相应的信号或跳闸命令通过B448C总线传输至216AB61O/P装置。至216DB61输入/输出单元。将保护功能O/P处的信号和跳闸命令分配给216AB61输出单元或216DB61 I/P信号和跳闸单元也由安装在216VC62a处理器单元中的软件。

The primary system c.t's and v.t's are connected directly to the
216GW61 input transformer unit. The signals of the measured
input variables are stepped down to a suitable level for processing by the electronic circuits (analogue signals) and transferred
via the system cable to the 216EA61 unit, which digitises them
and transmits them to the B448C parallel bus.The digitised measured variables derived from the primary system quantities are continuously compared by the processing unit
216VC62a with the pick-up settings of the protection functions. If
a protection function picks up, the corresponding signal or tripping command is transmitted via the B448C bus to the 216AB61
O/P unit resp. to the 216DB61 I/O unit. The allocation of the signals and tripping commands at the O/P’s of the protection functions to the various channels of the 216AB61 output unit or of the
216DB61 I/P signal and tripping unit is also determined by the
software installed in the 216VC62a processor unit.
The output signals from the 216AB61 unit (signalling channels)
and 216DB61 unit (trip channels) control the auxiliary relays
K1...K16 of the 216GA61 O/P relay unit or 216GA62 tripping relay unit. The auxiliary relays' contacts are potentially-free and
wired to terminals for connection to external signalling and tripping circuits.
The external input signals connected to the protection energise
the auxiliary relays K1...K16 in the 216GE61 I/P relay unit. The
potentially-free contacts of K1...K16 transmit the external signals
to the 216DB61 unit and thence to the B448C bus. By appropriate configuration of the software in the 216VC62a processing
unit, external signals can be assigned to the various protection
functions, e.g. for logical combination (interlocking and blocking)
with trip signals or for exciting the tripping channels 1...8.
Tripping circuits 1...8 can be directly energised by all or just
some of the I/P channels 1...10 (K1...K10) of 216GE61 via the
diode matrix (tripping logic) of 216GA62 (see Section 2.6.).
Provision is also made for some of the channels 9...16
(K9...K16) of 216GE61 to be used for supervising the external
tripping circuits 1...8 instead of for the connection of external inputs. This is an option, which must be specified in the order to
enable the corresponding wiring to be included when engineering the protection.In order to supply the electronic units with power the protection
must be connected to an external auxiliary d.c. supply (station
battery). The auxiliary d.c. supply unit 216NG61, 216NG62 or
216NG63 (DC/DC converters) steps the station battery voltage
down to 24 V and provides electrical insulation between input
and output voltages. The 24 V supply is distributed to the units
inserted in the protection equipment rack via the B448C parallel
bus. The 216NG61, 216NG62 or 216NG63 power supply unit
also supplies the electronic circuits on the I/O units. A 216MB66
equipment rack can be equipped with just one or with two redundant 216NG61, 216NG62 or 216NG63 auxiliary d.c. supply units. Redundant units can be connected to the same or to two
different station batteries.
