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.
For the digital outputs (without diagnostics) four-conductor devices (V+; 0 V;
signal; ground) are standard.
In a node using both two and four channel digital modules, a two channel mo-
dule must be on the left of a four channel module. The four channel modules
do not have a ground connection.
All digital outputs are short-circuit protected.
Attention
In case of overloads a supply module with fuse (750-601) must be connected
on the line side to protect the output modules.
The indicated output values have been determined for 100% duty cycle.
However, in case of the 2 A versions it is possible to operate single channels at
higher load currents, however always verify that the total current does not ex-
ceed 4 A per module. Example: 2x2A (standard); 1x3.5A; 1x0.5A (total cur-
rent: 4 A).
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.
The output module can operate with all buscouplers of the
WAGO-I/O-SYSTEM.
