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.
Isolation and conversion of 0 … 20 mA, 4 … 20 mA and 0 … 10 V standard signals with high measurement accuracy requirements. At the same time, best possible protection of personnel and equipment must be guaranteed.
The standards governing the erection of installations demand protective separation according to EN 61140. The tightly dimensioned installation space on the mounting rail must be optimally used.
Procurement logistics and stockkeeping demand a universal product which covers all common signal combinations and which can be used around the world with the broad-range power supply.
In spite of the just 6 mm wide modular housing, VariTrans A 21000 meets the requirements of EN 61140 regarding protective separation up to an operating voltage of 300 V. The test voltage is 2.5 kV AC.
Very small leakage capacitances also ensure that high transient common-mode interferences can be isolated reliably and don’t lead to system malfunctions. Standardization and flexible signal conversion are optimally implemented by the calibrated range selection – on-site calibration becomes superfluous.
