  • This product is a standard signal isolator. The use of electromagnetic isolation principle, can output DC current or voltage signal after electrical isolation of the input DC current or voltage signal.  Its input, outputs and power supply are electrically isolated from each other. It is especially suitable to use in these devices, which requires electrically isolated, such as sensors, transducers and meters. It may be widely used in measuring and controlling systems with PLC, computer and automatic control systems.
