The ET10 control board has 48 galvanic isolated binary inputs, 12 groups of 4 inputs each. Each group has a common LED wire and separate power supply pins so inputs can be powered from different power sources. Using PNP and NPN sensors simultaneously is possible too. | The ET10 control board has 48 galvanic isolated binary inputs, 12 groups of 4 inputs each.
