ES-5419 Rev.11
F2SN
Super-mini Signal Conditioners F2 Series
INPUT LOOP POWERED ISOLATOR
Functions & Features
• Loop-powered design eliminates output loop power supply
• Two isolators housed in one enclosure
• 350 Ω output drive with 4 – 20 mA
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
