Technical description
This description is only intended for hardware version X X X X 2 A 0 0 - - - -.
The serial number can be found on the right side of the module.
The input channels are differential inputs and they have a common ground
potential.
The inputs are connected to +I and -I. The shield is connected to "S". A capa-
citive connection is made automatically when snapped onto the DIN rail.
These I/O modules are not provided with integrated power jumper contacts.
The power supply is made by the data contacts with a DC-DC converter. The
modules can work self-supporting.
The input module can operate with all buscouplers of the
WAGO-I/O-SYSTEM (except for the economy type)
.
