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
