VariTrans A 20300

Signal Doubler

Signal doublers with two switchable calibrated outputs in a 6 mm housing, also for applications with high 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 space
    4-port isolation in a 6-mm modular housing
  • Signal doubling
    combined with signal conversion
  • Load increase
    up to 1000 ohms possible for inputs with high input impedances
  • Standards-compliant personal protection
    through protective separation according to EN 61140
  • Flexible use
    with DIP switches accessible from the outside
  • Calibrated range selection
    without complicated trimming
  • Low-cost solution
    Only one compact, low-cost device is required instead of two 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 standard 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 module, the input, both outputs, and the power supply are safely decoupled from one another (four-port isolation).
