18. Hardware descriptionHardware modulesPower supply module PSMThe power supply module is used to provide the correctinternal voltages and full isolation between the terminal andthe battery system. An internal fail alarm output is available.Binary input module BIMThe binary input module has 16 optically isolated inputs andis available in two versions, one standard and one withenhanced pulse counting capabilities on the inputs to beused with the pulse counter function. The binary inputs arefreely programmable and can be used for the input of logicalsignals to any of the functions. They can also be included inthe disturbance recording and event-recording functions. Thisenables extensive monitoring and evaluation of operation ofthe IED and for all associated electrical circuits.Binary output module BOMThe binary output module has 24 independent output relaysand is used for trip output or any signaling purpose.Static binary output module SOMThe static binary output module has six fast static outputsand six change over output relays for use in applications withhigh speed requirements.Binary input/output module IOMThe binary input/output module is used when only a few inputand output channels are needed. The ten standard outputchannels are used for trip output or any signaling purpose.The two high speed signal output channels are used forapplications where short operating time is essential. Eightoptically isolated binary inputs cater for required binary inputinformation.mA input module MIMThe milli-ampere input module is used to interface transducersignals in the –20 to +20 mA range from for example OLTCposition, temperature or pressure transducers. The modulehas six independent, galvanically separated channels.Optical ethernet module OEMThe optical fast-ethernet module is used to connect an IED tothe communication buses (like the station bus) that use theIEC 61850-8-1 protocol (port A, B). The module has one ortwo optical ports with ST connectors.Serial and LON communication module SLM, supports SPA/IEC 60870-5-103, LON and DNP 3.0The serial and LON communication module (SLM) is used forSPA, IEC 60870-5-103, DNP3 and LON communication. Themodule has two optical communication ports for plastic/plastic, plastic/glass or glass/glass. One port is used for serialcommunication (SPA, IEC 60870-5-103 and DNP3 port ordedicated IEC 60870-5-103 port depending on ordered SLMmodule) and one port is dedicated for LON communication.Line data communication module LDCMEach module has one optical port, one for each remote endto which the IED communicates.Alternative cards for Medium range (1310 nm single mode)and Short range (850 nm multi mode) are available.Galvanic RS485 serial communication moduleThe Galvanic RS485 communication module (RS485) is usedfor DNP3.0 communication. The module has one RS485communication port. The RS485 is a balanced serialcommunication that can be used either in 2-wire or 4-wireconnections. A 2-wire connection uses the same signal for RXand TX and is a multidrop communication with no dedicatedMaster or slave. This variant requires however a control of theoutput. The 4-wire connection has separated signals for RXand TX multidrop communication with a dedicated Masterand the rest are slaves. No special control signal is needed inthis case.GPS time synchronization module GTMThis module includes a GPS receiver used for timesynchronization. The GPS has one SMA contact forconnection to an antenna. It also includes an optical PPS ST-connector output.IRIG-B Time synchronizing moduleThe IRIG-B time synchronizing module is used for accuratetime synchronizing of the IED from a station clock.Transformer input module TRMThe transformer input module is used to galvanically separateand transform the secondary currents and voltages generatedby the measuring transformers. The module has twelve inputsin different combinations of currents and voltage inputs.Alternative connectors of Ring lug or Compression type canbe ordered.High impedance resistor unitThe high impedance resistor unit, with resistors for pick-upvalue setting and a voltage dependent resistor, is available ina single phase unit and a three phase unit. Both are mountedon a 1/1 19 inch apparatus plate with compression typeterminals.Layout and dimensionsDimensionsBay control REC670 1MRK511232-BEN EPre-configuredProduct version: 1.220 ABB
