4. system galvanic isolation barriers between the input the output and the power supply circuits The DRF series of Isolated Signal Converters offer an excellent relation between signal conversion speed and measurement accuracy Offering up to a 0 2 accuracy and down to 70ms response time these units can process information coming from probes or transducers in such a way that can be quickly retransmitted in a fast and accurate form to remote data acquisition systems or PLC s The isolated signal converters ofthe DRF series are ideal to integrate into 12 bit data acquisition systems Its powerful galvanic isolation of 3500 V introduces high security tothe measuring systems preventing the propagation of those phenomenon which usually cause damage such as transient peaks or energy shocks in any of the circuits of the system The galvanic isolation also acts as a strong CE barrier The decoupling created between the circuits avoids pernicious effects on the output such as ground loops or signal leaks which distort the acquired data and are extremely difficult to isolate once introduced into the signal DR a The isolation offered by the DRF series of Isolated Signal Converters is a 3 way isolation Thus all the benefits exposed above are applicable to any of the three circuits composing the instrument input output and power Recalibration ofthe instruments is realized ina fast and easy way Opening the front cover gr
