Configuration Concept

Theinputs/outputsoftheMSRecoStageControllerhavenofixedfunctions.TheMSRecoworkswithan"open configuration"concept.Thismeansthatallavailableinputsandoutputs(relays, sensors, digital inputs, analogue output)canbeconfiguredtoworkwithanyavailablecontrolfunctionorcontrolcircuit.Temperature SensorsSensorscanbeusedtocontrol,orsimplytodisplay.Digital inputs (DI, Optocoupler inputs)Each digital input can be assigned to one of thepossiblefunctions.Relay OutputsEachrelaycanbeusedtocontroloneofthepossiblefunctionsandcanalsobeswitchedonmanually.

The relay outputs #2, #3 and #5 are Solid State Relays (SSR) with a lower contact rating than the standard relay outputs. They can be used for any function within the specified current range.

Networking of controllers via E-LINK

The MSR eco can be networked together withotherELREHAcontroldevicesviaanRS-485-2-wiredatabus,whichenablesupto78controllerstocommunicate.Forcommunication,theE-LINKtransmissionprotocolisused.Each controller in a network has its individualaddress('P90',ModePage).
