Technical description
The power supply is connected to the power jumper contacts on each I/O mo-
dule for the respective operating voltage. Power connections are made auto-
matically from module to module when snapped onto the DIN rail, with power
supplied through a power feed module.
All 2-channel digital inputs are 4-conductor devices allowing the direct con-
nection of 4-conductor sensors with the terminations V+, 0V, ground and si-
gnal.
The positions of the different I/O modules in the configured node/station are
selectable by the user. A block type configuration is not necessary.
These input modules can operate with all buscouplers of the
WAGO-I/O-SYSTEM.
