Digital isolator with power supply

May 2011 Data Acquisition & Telemetry

VariTrans A 21000 from Knick is a compact standard signal transmitter with three-port isolation in a space-saving 6 mm housing. Calibrated range selection makes time consuming parameter setting and adjusting unnecessary. With an integrated universal power supply for international use, the device can be operated from either 24-110 VDC or 110-230 VAC.

The new VariTrans amplifier meets the requirements for personnel and plant safety with protective separation according to EN 61140 up to 300 V. The test voltage is 2,5 kV AC.

Since the devices do not require ventilation space when rail-mounted, control cabinets can be densely packed. The low self-heating also leads to a long operating life. Knick provides a five-year warranty on the units.
