Phoenix Contact MINI MCR Series Signal Conditioner, Current Input, Current Output, 18V Supply, ATEX

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.

Looking for a way to solve ground-loop problems? Take charge with this Phoenix Contact signal conditioner. It has built-in isolation that cuts noise between the elements of large electrical setups. As the input and output remain constant at 0 to 20m, it does this without compromising the current in your circuit.
The unit has an IP20 rating, meaning it's touch-proof and protected against tools larger than 12mm, so you can get on with maintenance safely. To save space on your DIN rail, it has compact dimensions of6.2 (W) x 93.1 (H) x 102.5mm (D) and you can mount it in any position. Components like this one are commonly used for circuit monitoring and industrial automation.

• 1.5kV AC test voltage for protection from electrical surges
• Easy compatibility with rigid and flexible conductors in a cross-section range between 0.2 and 2.5mm²
• Snaps onto a standard 35mm DIN rail to make set-up speedy
• Withstands temperatures between -20°C and +65°C, so it's suitable for use in challenging conditions
• Loop-powered type removes the need for an external energy source
