Digital IO modules
To transform Revolution Pi into an industrial control unit, various digital I/O modules can be connected to the base module RevPi Core. The I/O modules come in three versions. All have the same 28-pin I/O connector at the front (connector with two rows of 14 pins each – two suitable 14-pin socket connectors with spring clamp contacts for the connection of up to 1.5 mm² stranded hookup wires are supplied). Apart from the standard version with 14 digital inputs and 14 digital outputs, there are also two special versions that exclusively have either 16 digital inputs or 16 digital outputs.
