* In comparison with the 500 series, there are less indication LEDs (15 instead of 18). However, these 15 LEDs are coming as a standard hardware, not an option as before. * * * * English and one additional language can be selected. * * * * * * In the future, there will be possible to see the last two disturbances – one at a time – at the bottom of the control screen. * To be able to see the list of events, one must configure the IED so that selected signals to be shown as events are connected to the DR function module. * Benefits and Conclusion The IED will be fully operational also if the HMI is faulty. * ABB Logo * The main purpose of the transformer module is to transform the voltages and currents from the VTs and CTs to a level that the IED can manage. The 12 analogue inputs are electrical connections to the respective CTs and VTs. The TRM has 12 input transformers. There are seven versions of the TRM available. One has maximum number of current inputs, i.e. 12 current inputs and no voltage input. One has maximum number of voltage inputs, i.e. 6 voltage inputs and 6 current inputs. The other five TRM versions have other combinations of current and voltage inputs. The TRM is connected to the A/D and NUM modules via the UBM. * The UBM connects the ADM to the TRM. The ADM has twelve analogue inputs. The ADM module input signals are voltage and current from the transformer module. Shunts are used to adapt the current signals to the electronic voltage level. The input signals pass an anti aliasing filter with a cut-off frequency of 750 Hz. Inputs signals are sampled with a sampling frequency of 5 kHz (100 samples per cycle). The AD converted signals pass a band pass filter with a cut-off frequency of 250 Hz and are down-sampled to 1 kHz in a FPSA before being transmitted to the main processing module (NUM). The ADM has one PMC mounting position and 2 PC*MIP mounting positions onto which mezzanine modules such as SLM or LDCM can be placed. The ADM is equipp
