V-care introduces micro-controller based Digital Current source unit which is the new addition to the product range of simulation accessories. This current Source gives out 0-20mA current output for a load of 0 to 500 Ohms maximum. The current output can be set by the front panel keys. A 4 -digit display will indicate the set current value with a settable resolution. This unit operates from 230V AC/24Vdc*/48Vdc** input and is housed in a half DIN ABS PLASTIC box. This unit finds its application in simulating field parameters for testing other units that accept a 4-20mA current input.
