Digital Outputs (Standard with diagnostics)

PN 750-506

Technical description:

The power supply is provided by a series-connected supply module for the respective operating voltage. Power connections are made automatically from module to module via the internal P.J.C.s when snapped onto the DIN rail.

Attention:

The lowest power jumper contact is not carried out for some modules (e.g. 4-channel)! A module which needs all contacts (e.g. 2 channel digital) may not be connected to the right hand side of modules which do not have 3 power jumper contacts (e.g. 4 channel modules).

Using the digital outputs with diagnostic bit outputs (750-506) allows verification 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 function module includes 2 digital outputs and 2 separate digital inputs. For the digital outputs with diagnostic four-conductor devices (V+; 0V; signal; ground) are standard. All digital outputs are short-circuit protected.

In case of overloads a supply module with fuse (750-601) must be connected on the line side to protect the output modules.

The standard numerical assignment for bus operations is from left to right, starting with the LSB. 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 considered accordingly in the configuration of the Node/station. The Output module can be connected to all buscouplers of the WAGOÇI/OÇSYSTEM.
