Description

A21000 Isolated Standard Signal Conditioner | Input and Output 0(4) … 20 mA or 0 … 10 V | Isolation up to 300 V

The first standard-signal isolation amplifier with broad-range power supply in the 6-mm class.

  • Broad-range power supply 
    24 to 110 V DC (+/-25 %) and 110 to 230 V AC (+/-10 %)
  • Standards-compliant personal and plant protection
    Protective separation according to EN 61140"
  • 3-port isolation
    Prevention of incorrect measure-ments caused by potential differences
  • Ideal value for money
    High accuracy and isolation – 2.5 kV AC test voltage
  • Easy installation
    DIN rail bus connectors allow for easy and extremely cost efficient connection of the power supply to several VariTrans A 21000 or other Knick products in 6 mm housings.
  • Cost reduction with smaller enclosure
    More channels per meter DIN rail thanks to space-saving 6 mm housing and closely packed mounting
  • Long service life
    Extremely low failure rate  (MTBF of 280 years) due to reduced self-heating
  • High accuracy and temperature stability
    Gain error 0.2 % and temperature coefficient 0.01 %/K
  • Calibrated range selection 
    without complicated readjustments
  • Easy configuration
    DIP switch accessible from outside
  • Adjustable or fixed-range models
  • International use
    UL approvals for US and Canada
  • 5-year warranty

The A21000 isolates, transmits and converts 0 to 20/4 to 20 mA and 0 to 10 V with a high level of accuracy. In spite of its modular housing being only 6 mm wide, the new VariTrans isolation amplifier provides maximum protection of personnel and equipment through protective separation up to a working voltage of 300 V conforming to EN 61140. The test voltage is 2.5 kV AC. It can be supplied with either 24 V DC or 230 V AC.

We look forward to hearing from you!
