The analog input module processes signals of a standard magnitude ±10V.
The input signal is electrically isolated and is transmitted with a resolution of
16 bits.
The internal system supply powers the module.
The input channels of the module have one common ground potential.
The 24V supply is derived from the power jumper contacts.
The shield (screen) is directly connected to the DIN rail.
