SIGNAL ISOLATOR, DUAL OUTPUT

SI4P is an independently powered isolator which provides both a fully isolated DC supply for energising a 2-wire transmitter while also transferring the transmitter current to two separate isolated output circuits driving loads upto1 kΩ.The input can also be a 0/4~20 mAcurrent source. Line fault detection feature (also isolated) is provided by an open collector which can be used to activate an alarm. When the input cable is broken, no current flows into terminal 8/10 and the line fault detection (LFD) output is OFF. When a current greater than 1 mAflows in the input, then LFD output is ON. Power supply required is 17~35 V DC / 85~265 V AC. An input protection option is also provided.
