MODEL: 15SN 15SN SPECIFICATIONS ES-0619 Rev.8 Page 1/2 http://www.m-system.co.jp/ Dual Channel Input/Output Isolators 15-RACK INPUT LOOP POWERED ISOLATOR Functions & Features

  • Loop-powered design eliminates output loop power supply
  • 500 V DC input-to-output isolation
  • 2 channels available; accomplishing economical and space-saving multi-input processing 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 MODEL: 15SN–A6[1]
