Digital Outputs (Solid State Relay)

PN 750-509

Technical Description

The power supply for the solid state relay module is connected by a series-connected supply module for the respective operating voltage of 230 V. 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).

The power supply of the control side is not made via the power jumper contacts but directly from the electronics. The respective output contacts of the switching element are therefore always positioned at the field side. One termination point of these contacts must be directly connected to the power supply. For the digital outputs 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 (750-609) must be

connected on the line side to protect the output modules.

The standard numerical assignment for Bus operation is from left to right, starting with the LSB. The positions of the different inputs in the configured station are via the user’s choice. A block type assembly is not necessary. The Output module can be connected to all buscouplers of the WAGOÇI/OÇSYSTEM.
