Loop Powered Isolator

Radix Electrosystems Pvt Ltd offers a current-to current loop powered isolator. It accepts an input of 4 to 20 mA and produces a 4 to 20 mA output with a transfer accuracy of 0.1%. The temperature coefficient of accuracy is 0. 1% per ?C, and the input voltage drop less than 4.5 volts. Any load of 0 to 500 ohms can be connected to the output without change of accuracy. This eliminates the need for load trimming at site. The input/output isolation is 1,500 V AC for 1 minute, and 250 V AC continuous. The instrument is housed in a 22 x 74 x 97 mm DIN rail enclosure. A model with 0 to 20 mA input/output and a low cost model with load trimming are also available.
