Isolated Standard Signal Conditioner

VariTrans A 21000

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

The VariTrans A 21000 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.

Facts

• 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 measurements 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

Signal Doubler

VariTrans A 20300

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
