6.1 General description
TheuidowratecontrollerType8750isacompletesystemfor
measuringandcontrollingthevolumeowofgasesaccordingtothe
dierentialpressureprinciple.ThesystemconsistsofanELEMENT
controlvalveType2301withtheprocesscontrollerType8693as
wellastwopressuresensors.Itissuppliedasafullyassembled

Options:
•Digitalinput
•Analogfeedback
•2digitaloutputs
•Buscommunication(EtherNet/IP,PROFINET,PRO-
