One Input Two Output DC Current Signal Isolator

The main function of the signal isolator is to isolated transmit the input DC voltage (current) signal into the standard current or voltage signal. The product contains an efficient micro power isolated power supply that provides an isolated power supply to the pre-stage primary sensor while powering the internal signal processing circuitry. The products are widely used in analog signal isolation conversion of industrial field, such as communications, power rail, industrial control and other automation and control fields.
