FP302 Foundation Fieldbus to Pneumatic Signal Converter.

In order to connect existing valve actuators to a FIELDBUS system, SMAR developed a FIELDBUS to pneumatic signal converter, with very low air consumption and a very stable output signal. A 0 to 100% digital signal from the FIELDBUS is converted into a 3 to 15 psi or 3 to 30 psi pneumatic signal according to a characteristic curve selected by the user. Besides the normal PID control function, linearization, master capability, alarms and damping, the FP302 offers signal limitation and reversing and many other features for valve actuation:

  • Output signal: 3 to 15 psi (default) or 3 to 30 psi (extended)
  • Supply pressure: 20 to 100 psi;
  • Vibrating resistant;
  • PID Controller;
  • Can be mounted in any position;
  • Accuracy: 0.4 % of the span.
