Active signal isolator is a mixture of (sensor output) analog voltage or current signal converted by the isolation accuracy, linearity matched hybrid integrated circuit. Products are mainly used in industrial control systems analog input and output control, internal systems via DSP, DA converter output signal PLC to display and adjustable output control other devices, monitoring and system field voltage, current, and various operating parameters External increase 4-20mA (0-20mA) / 0-5V standard signal interfaces. The IC is in line with standard Sip12 Pin retardant UL-94 package occupies less PCB area. Internal load monitoring instrument can be installed in parallel to achieve multi-channel signal isolation and conversion. Compared with optical isolation products with better accuracy, linearity and temperature drift characteristics, and can achieve zero gain, full-scale adjustment-free, square wave field use and enhanced user reliability and stability. Category Isolators can be divided into active and passive isolator isolators.
