Base Binary Outputs; Base Power Supply Outputs; Base Member Interfaces; Serial Interface Rs422/485 - ECOLAB Versatronic Betriebsanleitung

( 3 ) The binary inputs IN 2 and IN 3, i.e. for the impeller for flow sensors (water meters) or magneto-inductive flow meters (square wave)
can be used. The input frequency range is dependent on the configured measuring principle in the Flow Function.
