ERL Input/Output Expansion Module ERL I/O Product Overview The ERL I/O expansion module is a digital input / output extension box which supports 128 physical digital inputs (DIs) and 15 output contacts. The I/O module uses IEC 61850-8-1 station bus protocol GOOSE messages to publish the state of the binary inputs to other ERL Devices and any other IEDs supporting IEC 61850 GOOSE subscriptions. The I/O module can also trigger on the state of digital inputs in GOOSE messages published by ERL devices and other IED’s to activate its 15 user configurable output contacts or create records on any of its 128 virtual input channels. The ERL I/O Expansion system consists primarily of the unit hardware and the TESLA Control Panel user interface software. TESLA Control Panel user interface software provides tools to configure the unit, retrieve and manage records and display real time digital status values. Control Panel also includes RecordGraph, a graphical record display and analysis software tool. ERL 61850 IED Configurator software provides tools to manage unit’s station bus configuration. Application: The ERL I/O module is to be used in any application where there is need for many status (DI) inputs – such as large substations and generating stations. By communicating these digital input statuses to multiple IED’s in the network it expands their access to such information and is a cheaper alternative to adding additional IED’s. It reduces the problems associated with having these multiple IED’s communicate with each other and also reduces the cost. The ERL I/O IED also provides alarm and control through its 15 output contacts and 15 subscription virtual channels for output contact control. ERL I/O Expansion Module 10 Year WARRANTY

Application with TESLA 4000 TESLA 4000 power system recorder has provision for up to 256 virtual inputs which can be mapped to receive and record the time and status of events contained in the IEC 61850 GOOSE messages published by the ERL I/O module. These messages are available for records and oscillography in the same way as the 64 physical status (digital) inputs of the TESLA. Connect two ERL I/O modules with each TESLA 4000 to monitor and record 256 additional digital inputs. Use the Windows based ERL 61850 IED Configurator to configure and map data between the ERL I/O IED and TESLA 4000....
