IF302 Current to FieldBus Converter The IF302 is from the first generation of Fieldbus devices. It is a converter mainly intended for interface of analog transmitters to a Fieldbus network. The IF302 receives a current signal, typically 4-20 mA or 0-20mA, and makes it available to the Fieldbus system. The digital technology used in the IF302 enables a single model to accept three inputs and also provide several types of transfer functions. Read more
