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
supplies through a power feed module.
Using the digital outputs with diagnostic output bits (750-507) allows verifi-
cation of the I/O channel by the connected bus.
Example: a short-circuit at the output or an open circuit will set the appropriate
error bit true indicating I/O failure. In this configuration the I/O-module inclu-
des 2 digital outputs and 2 separate digital inputs. For the digital outputs with
diagnostics four-conductor devices (V+; 0V; signal; ground) are standard. 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 positions of the different I/O modules in the configured node/station are
selectable by the user. A block type configuration is not necessary.
When using I/O modules with diagnostics, the existing inputs must be consi-
dered accordingly in the configuration of the Node/station.
The output module can operate with all buscouplers of the
WAGO-I/O-SYSTEM.
