Loop Isolator Input = 0(4) ... 20 mA Incresed Isolation test voltage can be up to 4kV (option 506) Working voltage up to 300V AC/DC Power is supplied by input signal.
The IsoTrans® A 47 advanced series of loop-powered isolators. An extremely high component density of 177 channels per meter of top-hat rail and excellent technical properties, such as protective separation, make the isolators unbeatable.
The modern modular housing with a width of 12.5 mm for 1 or 2 channels and 22.5 mm width for 4 channels with practical plug-in terminals allow simple and quick assembly or prewiring of the enclosure.
The IsoTrans® A 47 obtains its power directly from the measuring signal as a voltage drop without falsifying it. There are no costs for a power supply and wiring. The IsoTrans® A 47 has virtually no self-heating that would cause the electronic components to age faster. Together with a patented circuit technology, this means maximum reliability. Due to this long service life, we give a 5-year warranty.
