Internal I/O Module
Inputs/outputs: | 8 digital inputs and outputs (24VDC) |
Communication protocol: | Modbus |
Expandable by adding: | Up to 7 extension modules each with 8 inputs and outputs; |
Current per output (internally limited by PTC): | 0,2A (500mA over all 8 outputs at a time loadable) |
Current consumption per input: | 7mA |

Outputs are protected against short circuits, overload, load dump (inductive voltage spikes) as well as the loss of ground connection.
Reversing the polarity of the supply voltage will destroy the internal soldered fuse.
