The positioner is controlled by a standard signal from a two-wire 4..20 mA current loop or digitally in accordance with the HART 6 specification. It can be also equipped with a two-wire, current (4..20 mA) position transmitter of the piston rod of the associated actuator. Current circuit of position transmitter is galvanically isolated from the input circuit of the control signal.The positioner can cooperate both with straight and reverse acting pneumatic actuators. The positioner can cooperate with single-acting actuators manufactured by Polna S.A., Samson, Arca Regler, Spiral-Sarco and double-acting actuators manufactured by Prema Kielce, Air Torque, Festo, Ebro Armaturen, El-0-Matic and by other manufacturers using proper mechanical coupling components.
