M2SN INPUT LOOP POWERED ISOLATOR

M2SN  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
