The analog input module powers the transducers, receives transmitted analog
signals, and with electrical isolation, transmits the signals to the fieldbus.
The 24V supply for the field is derived from the module's power jumper
contacts.
The shield (screen) is directly connected to the DIN rail.
At approx. 25mA, the overload protection switches the measurement input
to a high-resistance state. Under normal operating conditions it will
automatically switch back.
This input module can supply the voltage for 2-wire transducers.
