ES-3319 Rev.8
TSN
Super-mini Two-wire Signal Conditioners T-UNIT
INPUT LOOP POWERED ISOLATOR
Functions & Features
• Loop-powered design eliminates output loop power supply
• 500 V DC input-to-output isolation
• Highdensity 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
