More info

The FI303 is a converter mainly intended for interface of a PROFIBUS PA system to control valves, or other actuators. The FI303 produces a 4-20 mA output proportional to input received over the PROFIBUS network.

The digital technology used in the FI303 enables 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. The FI303 has three outputs, reducing the cost per channel.
