MODEL: KSN KSN SPECIFICATIONS ES-3514 Rev.9 Page 1/3 http://www.m-system.co.jp/ Plug-in Signal Conditioners K-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 (1.97) 123 (4.84) (3.15) mm (inch) K-UNIT MODEL: KSN–2[1][2]
