IF303
Current to Profibus PA Converter
The IF303 is a converter mainly intended for interface of analog transmitters to a PROFIBUS system. The IF303 receives a current signal, typically 4-20 mA or 0-20 mA, and makes it available to the PROFIBUS PA network. The digital technology used in the IF303 enables a single converter to accept three inputs and also provide several types of transfer functions.
This provides an easy interface between the field and the control room and also includes several interesting features that considerably reduce the installation, operation and maintenance costs.
