mA - Isolating Repeater Series 9164/13-20-55

mA - Isolating Repeater Series 9164/13-20-55

Series 9164/13-20-55

  • Interconnection of two mA-sources and active 2-wire inputs is possible
  • Ideal solution for integrating 4-conductor measuring transmitters into analogue input supplies
  • Bidirectional HART transmission 4 ... 20 mA
  • Galvanic isolation between input and output

Basic function: Analog signal transmission 4 mA ... 20 mA for 4-wire transmitters with HART communication, 1 channel.

The mA - isolating repeaters are used for connection of 4-wire transmitters to active 2-wire inputs (source) as well as to galvanic isolation.

The devices bidirectionally transfer a superimposed HART communications signal.
