16.2 Hardware modules IP14529-1 v116.2.1 Overview M11562-3 v10Table 525:Basic modulesModule DescriptionPower supply module (PSM) Including a regulated DC/DC converter thatsupplies auxiliary voltage to all static circuits.• An internal fail alarm output is available.Numerical module (NUM) Module for overall application control. Allinformation is processed or passed through thismodule, such as configuration, settings andcommunication. The module provides four SFPsfor Ethernet traffic.Local Human machine interface (LHMI) The module consists of LEDs, an LCD, a pushbutton keyboard and an ethernet connector usedto connect a PC to the IED.Transformer input module (TRM) Transformer module that galvanically separatesthe internal circuits from the VT and CT circuits. Ithas 12 analog inputs.Analog digital conversion module (ADM) The module converts the VT and CT analogsignals from the TRM to digital signals processedby the NUM. Carrier for communication boards.Note: TRM module is not included in SAM600-IO,so ADM module is only used for internalcommunication carrier for IO modules.Combined backplane module (CBM) The module has two main purposes: to distributesupply voltages from the PSM to the othermodules and to act as a communication carriervia its two buses, CompactPCI for fast I/O andcommunication and CAN for slow I/O.Universal backplane module (UBM) The module is used to interconnect the TRM andthe ADM. It also connects the NUM with the LHMITable 526:Application specific modulesModule DescriptionBinary input module (BIM) Module with 16 optically isolated binary inputsBinary output module (BOM) Module with 24 single outputs or 12 double-polecommand outputs including supervision functionBinary I/O module (IOM) Module with 8 optically isolated binary inputs, 10outputs and 2 fast signalling outputs.Serial SPA/LON/IEC 60870-5-103communication modules (SLM)Used for SPA/LON/IEC 60870–5–103communicationOptical Ethernet SFP Small form factor pluggable for EthernetcommunicationTable continues on next page1MRK 511 424-UEN B Section 16IED hardwareBay control REC650 2.2 IEC 647Technical manual
