Signal Isolator

SI-XX Signal Isolator

SI-XX Signal isolator is a universal Input Signal Isolator that dramatically simplifies the wiring works in the field, and also saves the types and amount of spare parts. This digital signal isolator suits for automatic control project, and implement a fast and flexible response for the industry field. Optional single or dual-channel models or loop-powered functions, with configuration software, can do site calibration and reset output signal.
