An Optically Isolated ( Galvanic Isolation) Input shield for Arduino Uno and/or other microprocessors, in Arduino Uno Shield form factor. The Shield provides 8 Optically Isolated Digital Inputs, via the use of an PFC8574 I2C IO Expander. Optical Isolation is provided with Opto-Couplers. The Shield is capable of accepting DC input voltage of between 3.0v and 32.0v. All Standard Arduino pins are broken out in a pass-through fashion. Can be powered by a maximum of 5v DC.
