Digital Outputs (Standard)

PN 750-501...504, 516, 519

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).

For the digital outputs (without diagnostic) 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.

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 750-516 is low-side switching. 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 exceed 3.5 A per module. Example: 2x2A (standard); 1x3.0A; 1x0.5A (total current: 3.5 A) 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.The Output module can be connected to all buscouplers of the

WAGOÇI/OÇSYSTEM.
