Phoenix contact [india] pvt ltd supplies buffer amplifiers.These new buffer amplifiers mcr-c/-dc from phoenix contact are used for the insulation and conversion of analogue standard signals which permitallow a particularly space-saving installation having with a width of only 12.5 mm.Buffer amplifiers are constructed designed for the three most common standard signals 0-20 ma, 4-20 ma and 0- 10 v, there are nine versions of the buffer amplifier. The 3-way insulation providesoffers the user a secure and precise signal transmission with a transmission error of less than 0.2 per cent. The pluggable connection technology also permitsallows rapid piggy backing of the 20-30 v dc power supply with prefabricated lines. Thereforethus, these new 3-way buffer amplifiers are particularly suitable for use in larger projects, eg, in the area of water/waste water treatment and sewage work technology.
