SI-XX Signal isolator

SI-XX Signal isolator

SI-XX Universal Input Signal Isolator dramatically simplify the wiring works in the field, also save the types and amount of spare parts. Suit for autoamtic control project, implement the fast and flexible response for industry field. Optional single or dual-channels models or loop-powered function, with configuration software can do site calibration and reset output signal.
