216NG61A HESG441633R1 HESG216875/K Input/Output module

Trip circuit… 8 can be activated directly by everyone, or it can be activated by just a few I/P channels 1… 10 (K1… K10) Diode matrix of 216GA62 (trip logic)(see Section 2.6). Provision is also made for certain channels 9… 16 (K9… K16) 216GE61 is used to supervise the external trip circuit… 8 instead of connecting to external input. This is an option that must be specified sequentially when designing protection so that the corresponding wiring should be included. In order to power electronic devices, protective devices must be connected to an external auxiliary DC power station battery).

The auxiliary DC supply unit 216NG61, 216NG62 or 216NG63 (DC/DC converter) steps the station battery down to 24v and provides the electrically insulated output voltage between the inputs. 24v power is allocated to each unit through B448C connected in parallel into the protective equipment rack in the bus. The 216NG61, 216NG62 or 216NG63 power supply unit also provides the electronic circuit on the I/O unit. The 216 mb66 equipment rack can be equipped with one or two redundant 216NG61, 216NG62 or 216NG63 auxiliary DC power units. Redundant units can be connected to the same or two different station batteries.
