A range of universal trouble-shooters
Our 2200- and 5000A-series constitute a complete range of isolators covering the entire spectrum within signal isolation.
The patented STREAMSHIELD principle is integrated in the 5000A-series and ensures high immunity against e.g.
conducted noise, transients and burst. The isolation modules handle the following functions:

• Signal adaptation
• Elimination of ground loops
• Scaling of process values
• Potential separation
• Galvanic separation
• Noise filtration

Easy configuration of the 5000A-series with PReset
Flexibility is one keyword for the 5000-series of signal isolators. Within a few minutes the modules are configured to the concrete application
with the user-friendly PReset software or dipswitches. Consequently, the user has easy access to:

• Inversion: When the relation between input and output is directly opposite. Example: A 4-20 mA input signal is inversed to 20-4mA.
• Signal scaling: If the focus area needs to be e.g. 4-8 mA the signal can be scaled.
• Custom linearization: At e.g. measurement in cylindrical, horizontal tanks the incoming signal curve has to be changed every now and then.Thus, the linearization capability must be used to convert the 4-20 mA signal from a vertical level sensor to a volume linear signal.

* Doubling: In some cases the conversion of an input signal to several output signals such as mA and V is appropriate. In signal isolators from PR electronics the doubled signals are galvanic protected.
