ES-0619 Rev.9
15SN
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
