Description

Acerca de este producto

aquí está todo lo que necesitas saber


The Siemens 6ES5951-7ND51 is a power supply module for the S5-115U range of programmable controllers. S5-115U controllers are modular in design and are made up of several components including power supply modules, a central processing unit (CPU), input and output modules (I/O), intelligent input and output modules, and communications modules.

The power supply modules convert  the external power supply to the internal operating voltage. In the case of the 6ES5 951-7ND51, the external supply voltage is 24V DC.

This power supply also has a lithium battery for backup of program memory, internal retentive flags, timers and counters in the event of a power failure. See more detailed technical information in the specifications table.
