2-4 L60 Line Phase Comparison System GE Multilin2.1 INTRODUCTION 2 PRODUCT DESCRIPTION22.1.2 ORDERINGThe L60 is available as a 19-inch rack horizontal mount unit or a reduced size (¾) vertical mount unit, and consists of thefollowing modules: CPU, faceplate, power supply, CPU, CTs and VTs, digital input and outputs, transducer inputs and out-puts, and inter-relay communications. Each of these modules can be supplied in a number of configurations specified at thetime of ordering. The information required to completely specify the relay is provided in the following tables (see chapter 3for additional details of relay modules).The L60 is specified with two CT/VT modules (8F and 8P). When the L60 is applied in two-breaker configurations (such asbreaker-and-a-half or ring configurations), the currents from the two CTs are summed internally within the relay or exter-nally. If the voltage is not supplies to the relay, some functions (such as distance, undervoltage, and synchrocheck) will notbe available.Order codes are subject to change without notice. See the GE Multilin ordering page athttp://www.gedigitalenergy.com/multilin/order.htm for the latest ordering options.The order codes for the horizontal mount units are shown below.Table 2–2: OTHER DEVICE FUNCTIONSFUNCTION FUNCTIONBreaker Arcing Current (I 2 t) Metering: Current, Voltage, Power, FrequencyBreaker Control Modbus CommunicationsBreaker Flashover Modbus User MapContact Inputs (up to 96) Non-Volatile LatchesContact Outputs (up to 64) Non-Volatile Selector SwitchControl Pushbuttons Open Breaker EchoCT Failure Detector Open Pole DetectorCyberSentry™ security OscillographyData Logger Pilot Scheme (POTT)Digital Counters (8) Setting Groups (6)Digital Elements (48) Time synchronization over IRIG-B or IEEE 1588Direct Inputs and Outputs (32) Time Synchronization over SNTPDisconnect Switches Transducer Inputs/OutputsDNP 3.0 or IEC 60870-5-104 Communications Trip BusEvent Recorder User Definable DisplayFault Location User Programmable LEDsFault Reporting User Programmable PushbuttonsFlexElements™ (8) User Programmable Self-TestsFlexLogic Equations Virtual Inputs (64)IEC 61850 Communications (optional) Virtual Outputs (96)Line Pickup VT Fuse FailureLoad EncroachmentTable 2–3: L60 ORDER CODES (HORIZONTAL UNITS)L60 - * ** - * * * - F ** - H ** - L ** - N ** - S ** - U ** - W/X ** For Full Sized Horizontal MountBASE UNIT L60 | | | | | | | | | | | | Base UnitCPU T | | | | | | | | | | | RS485 and Three Multi-mode fiber 100Base-FX (SFP with LC)U | | | | | | | | | | | RS485 with 1 100Base-T Ethernet, SFP RJ-45 + 2 100Base-FX Ethernet, multimode, SFP with LCV | | | | | | | | | | | RS485 with 3 100Base-T Ethernet, SFP with RJ-45NOTE
