The solid state relay provides complete isolation between the input and output terminals. The input can be driven by an AC or DC voltage from 4 to 200 Volts Peak. The drive current required is 1mA minimum. This makes the solid state relay an ideal control module for low power devices. A typical application would be an AC or DC load which requires a microprocessor to control the on and off states. Another application involves using the solid state relay to interface between a TTL or CMOS output, such as a rotary encoder or counter, and a data line going through a noisy environment.
