Acrel new designed analog isolation barrier electrical in plc used in petrochemical productions
Connected between intrinsically safe circuits and non-intrinsically safe circuits. A device that limits the voltage or current supplied to an intrinsically safe circuit within a safe range. Safety barrier is a general term, divided into zener safety barrier and isolation safety barrier, isolated safety barrier is referred to as isolation barrier.
