The ABUS USI Series Universal Smart Isolator being programmable through Handheld Configurator USI-C can be fit into major of industrial applications operating with different signals. It can be ordered to accept up to 2 inputs and provide up to 3 outputs. The input signals can be non-linear input such as resistance temperature detector, thermocouple or linear current or voltage. Signal of one-way, two-way or three-way current or voltage, isolated by transmitting output provides good electric isolation between input, output and power. It can be used as a temperature transmitter,convertor, signal isolator or signal conditioner according to the application.
