Isolation Products

The Extron Signal Isolator is used to isolate and condition DC voltage and current signals which are derived from transducers, microprocessors, motors, and process controllers. The output of the signal isolator is connected to the input of any variable speed motor control with a voltage following input. The isolator is versatile since it can accommodate a wide range of input voltages and in addition, a wide range of input current signals. In the current mode, the units can be calibrated so that a 4-20mA input yields a 0-10 VDC output. Extron offers several versions of signal isolation modules for use in applications such as industrial control, instrumentation, and system modification.
