Isolate, Convert, Boost, and Rescale Process Signals

Even when you are not working with high voltage, it is useful to be able to isolate signals by kV.

The model TEVL-HVDC accepts a DC voltage input and provides an optically isolated DC voltage or current output that is linearly related to the input. This module is unique because it is field rangeable for voltage inputs from 100 VDC to 2000 VDC. Typical applications include signal isolation, signal conversion, signal attenuation or a combination of the three.The optical isolation between input and output makes it useful for ground loop elimination, common mode signal rejection or noise pickup reduction. The power supply is isolated, resulting in full 3-way (input, output, power) isolation.

The input and output range settings are configured by the factory to customer requirements, but they can be reconfigured in the field via internal switches. Common range settings are on the module label. A user specified range is available that can be factory configured to meet your specific requirements

  • High Voltage Input Ranges from 100 VDC to 2000 VDC

  • High Input Impedance

  • 2000 V Full Input/Output/Power Isolation
