The flush-mounting Analog Module is used to read 2 separate analog values 0-5V into the subnet. The resolution of each channel is 8 bits. The individual analog channels are available in the Master Module for further links, depending on the application purpose. At the same time, 2 digital inputs and 2 digital outputs are available, at which e.g. buttons and signal lamps can be connected.
