Digital Outputs 750-519

4.3.1.1.12 4 Channel Digital Outputs

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.

For the digital outputs (without diagnostics) four-conductor devices (V+; 0 V; signal; ground) are standard. In case of 12 mm wide 4-channel digital output modules it is not possible to use 4-conductor devices. 4 signal outputs, 2xV+ and 2x0V are provided.

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 module 750-519 is high-side switching.

The indicated output values have been determined for 100% duty cycle.

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.

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 differential inputs and they have a common ground potential.

The inputs are connected to +I and -I. The shield is connected to "S". A capacitive 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 modules can work self-supporting.

The input module can operate with all buscouplers of the

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

Numerical format

The digitized measured value is stored in a data word (16 bit) as an input byte 0 (high) and as an input byte 1 (low). The value with a 12 bit resolution is illustrated on bit B3 ... B14. The three low value bits (B0 ... B2) are only used in the event of an error.

Some fieldbus systems process status information to the input channel using a status byte
