2864419, Phoenix Contact Passive loop Isolator, 0 → 20 mA Input, 0 → 20 mA Output

Passive 4-20mA Loop Isolator

The 2864655 from Phoenix Contact is a 2-channel, loop powered passive isolator. This module is designed to electrically isolate current signals without an auxiliary power. Phoenix's 2864655 doesn't require any additional auxiliary voltage and has a voltage drop of just 1.7V. Not to mention, this module has 2 channels and a very slim 6.2 mm width housing. It has an ATEX zone-2 (potentially explosive areas) installation approval and is easily mounted on a DIN rail.
The 2864655 can isolate and filter standard current signals from 0mA up to 20 mA.

Features and benefits:

• 2 channels on a housing of only 6.2 mm


• No need for any additional auxiliary voltage


• Voltage drop at isolating amplifier of just 1.7 V


• Supplied by an input loop


• ATEX rating allowing for installation in zone 2 areas (potentially explosive areas)


• Mounted on either TBUS connector or straight onto DIN rail
