MODEL: FSN FSN SPECIFICATIONS ES-1419 Rev.10 Page 1/3 http://www.m-system.co.jp/ Space-saving Plug-in Signal Conditioners F-UNIT INPUT LOOP POWERED ISOLATOR Functions & Features

  • Loop-powered design eliminates output loop power supply
  • 500 V DC input-to-output isolation
  • 2 isolators housed in one enclosure
  • 350 Ω output drive with 4 – 20 mA
  • High-density mounting Typical Applications
  • Isolation between control room and field instrumentation, between telemetering system and input device
  • Eliminates ground problems in existing systems thanks to easiness of application without requiring additional power wiring 26 (1.02) 100 (3.94) mm (inch) 137 (5.39) MODEL: FSN–[1][2]
