The Task
Isolation and, if necessary, conversion of 0 ... 20 mA, 4 ... 20 mA as well as 0 ... 10 V standard signals. If you have limited space and budget, there could still be difficulties when it comes to selecting a suitable isolator despite the standard requirements for transfer in the selection.

The Problems
Up to now the only way of reducing costs substantially was to opt for low quality products. As a large number of different signals also required a large number of isolators, this also led to considerable stockkeeping costs.

The Solution
With its extreme compactness and low self-heating, the new standard-signal isolator from Knick sets new standards. The VariTrans® B 10000 is available with nine selectable, calibrated ranges or as one of eight different variants with fixed settings. In any case it has an extremely attractive price.

The Housing
Measuring only 6 mm, the closed modular housing of the VariTrans® B 10000 allows up to 163 active isolation amplifiers per meter top-hat rail. A pluggable cross-connection for power supply ensures quick and therefore inexpensive mounting.

The Advantages
In spite of the reduced space, the VariTrans® B 10000 provides true 3-port isolation between input, output, and power supply to prevent parasitic voltages.

The Technology
Analog signal processing with transformer isolation ensures excellent signal transmission. The input and output ranges can easily be selected using DIP switches.
