6SN

Field-mounted Two-wire Signal Conditioners 6-UNIT

INPUT LOOP POWERED ISOLATOR

Functions & Features
• Loop-powered design eliminates output loop power supply
• 500 V DC input-to-output isolation
• 350 Ω output drive with 4 – 20 mA
• Rugged enclosure
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
