12. tput and the power supply circuits The ISC series of Isolated Signal Converters offer an excellent relation between signal conversion speed and measurement accuracy Offering a 0 2 accuracy and up to a Oms response time depending on the model 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 of the ISC series are ideal to integrate into 12 bit data acquisition systems Its powerful galvanic isolation of 3 500 V introduces high security to the measuring systems preventing the propagation of those phenomenon which usually cause damage to the remote system 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 input output and power 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 The isolation offered by the ISC 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 of the instruments is realized in a fast and easy way Opening the front cover grants a
