Linear actuators DFPI

Linear actuators DFPI DFPIs are adjustable linear actuators. Product versions with an integrated displacement encoder DFPI-...-E-... are available. The displacement encoder integrated in the DFPI-...-E-... version returns an ana-logue voltage or current signal proportional to the position of the piston. This can be used for operation with an external positioner. The positions are specified via an analogue setpoint signal 4 ... 20 mA. The position feedback uses an analogue feedback signal of 4 ... 20 mA. The feedback signal guarantees high reliability and simple diagnostics for the operator....
