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