FRI303
FRI303 PROFIBUS PA Remote I/O
The FRI303 PROFIBUS-PA Remote I/O makes the integration of Profibus and conventional I/O easy. FRI303 is a PROFIBUS PA device that has two built-in relays and two dry contact inputs making integration of PROFIBUS PA and conventional devices such as on/off sensors, solenoids, on/off valves, electrical actuators, motors, pumps, starters, etc.
The FRI303 can be located at the field, mounted close to the conventional devices without the need to run the conventional wiring to the control room. The FRI303 is an integral part of SYSTEM302 but also integrates into other systems supporting Profibus.
