A20300 Signal Doubler | Input 0(4) … 20 mA or 0…10V | 2x 500 ohms output load

Description

A20300 Signal Doubler | Input 0(4) … 20 mA or 0…10V | 2x 500 ohms output load

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

  • Safety in the smallest space
    4-port isolation in 6 mm modularhousing
  • 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 A20300 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).
