This section provides information on the application, design and
principle of operation of the SIMATIC S5 951 load power supply
module (6ES5-951-4LB11).
The load power supply module can be used with a choice of input
voltage of 120 V or 230 V AC. It supplies a floating, electronically
stabilized output voltage of 24 V, and can be used with SIMATIC S5
systems to supply power for load circuits and enable inputs of
modules of the U Periphery.
The load power supply module has safe electrical separation to
VDE 0160.
The module is designed in the double Eurocard format for the ES 902
packaging system.
A 20-pin front connector contains all the terminals for the supply
voltage, DC voltage outputs, signalling output and inhibit inputs.
The module is two slots wide (40 mm).
