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 single ended and they have a common ground potential.

The inputs are connected to +I and ground. The shield is connected to "S". The 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 input module can operate with all buscouplers of the

WAGO-I/O-SYSTEM (except for the economy type).
