Signal Doubler

VariTrans A 20300

Signal doublers with two calibrated switchable outputs in a 6-mm housing, also for applications with high-level output loads.

The VariTrans A 20300 signal doubler is an extremely compact product which also provides a cost-effective solution to the problem of isolating and transmitting 0(4) to 20 mA and 0 to 10 V standard signals to two 0(4) to 20 mA output channels with galvanic isolation of the input, outputs, and power supply.
Its input, both outputs, and power supply are decoupled from one another (four-port isolation).

Facts

  • Safety in the smallest of spaces:
    4-port isolation in a 6-mm housing
  • Signal doubling combined with signal conversion
  • Load increase up to 1000 ohms possible for inputs with high input impedances
  • Personal protection conforming to standards through protective separation according to EN 61140
  • Flexible use with DIP switches accessible from the outside
  • Calibrated range selection: no cumbersome calibrating required
  • Low-cost solution:
    only one compact, low-cost device is required instead of 2 conventional isolators
  • International use: UL/CSA approvals

5-year warranty

 


The Task
Isolation and transmission of 0(4) … 20 mA and 0 … 10 V standard signals in two 0(4) … 20 mA output channels  with galvanic isolation between input, outputs and power supply.


The Problems
Measuring and control engineering frequently requires an analog stan-dard signal to be processed at two points, i.e., by two devices, with both devices needing to receive the same signal.  To prevent falsified signals and in particular, in the event of errors, interaction or even damage, it makes sense to isolate signals and devices galvanically from one another.


The Solution
The VariTrans A 20300 signal doubler is an extremely compact product which also provides a cost-effective solution to the problem. In this mod-ule, the input, both outputs, and the power supply are safely decoupled from one another (four-port isolation).
