SITRANS I300 was developed for intrinsically safe operation of 4-wire devices in the hazardous
area. Examples for 4-wire devices are Siemens flowmeters with Modbus output as well as
BACnet, or PROFIBUS RS 485-IS devices. The SITRANS I300 isolating power supply has to
be inserted between the EIA-485 Master and the flowmeter.

Application of the SITRANS I300
The SITRANS I300 limits the energy flow into the hazardous area. Therefore it prevents the
inflammation of a potentially explosive atmosphere.
