  Analog output 0/4 to 20 mA

  The output isolators are used for intrinsically-safe operation of valve positioners, i/p converters or indicators.

  Operation of intrinsically-safe HART valve positioners (e.g. SIPART PS2) is also possible. The units transfer a superimposed HART communication signal bidirectionally.

  Дизайн

  The isolating transformer HART consists of a compact plastic housing (IP30) and is equipped with push-in screw terminals.

  On the front are a green LED for indicating the power supply status and a red LED for signaling errors.

  The auxiliary power supply can be connected individually using push-in screw terminals or jointly for up to 40 units using pac-Bus.
