New version module available from Veederline

TEVL-HVDC module

The 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 this module useful for ground loop elimination, common mode signal rejection or noise pickup reduction.

The module power supply is isolated, resulting in full 3-way (input, output, power) isolation.

The TEVL-HVDC 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.

TEVL exclusive features include two LoopTracker LEDs and a functional test pushbutton.

The LoopTracker LEDs (green for input, red for output) vary in intensity with changes in the process input and output signals.

Monitoring the state of these LEDs can provide a quick visual picture of your process loop at all times.

The functional test pushbutton provides a fixed output (independent of the input) when held depressed. The test output level can be field-adjusted via a multi-turn potentiometer.

Both the LoopTracker LEDs and functional test pushbutton greatly aid in saving time during initial startup and/or troubleshooting.

The TEVL-HVDC available from Veederline clips to an industry standard 35mm DIN rail. The housing also allows for surface mounting.

Differentiate features:

• High voltage input ranges from 100 VDC to 2000 VDC
• 7 standard or 1 user specified input ranges
• Field selectable I/O ranges
• Input: 0-100 VDC to 0-2000 VDC
• Output: 0-1 VDC to ±10 VDC or 0-2 mA to 0-20 mADC
• High input impedance
• 2000 V full input/output/power isolation
• 55mm wide DIN style package
• I/O LoopTracker LEDs and functional test pushbutton
• Output linearity: better than ±0.1% of span
• Temperature stability: better than ±0.02% of span per °C
• Free factory: input and output input and output calibration
