Siemens PCS 7 manual AS 488/TM system unit

SIMATIC PCS 7 cabinet design

AS 488/TM system unit

•DC 24 V or AC 120/230 V power supply: depending on the in- put voltage, the AS 488/TM can be equipped either with a PS 407 power supply module (AC 120/230 V supply) or a PS 405 power supply module (DC 24 V supply), each rated at 10 A. These supply the AS 488/TM modules with the DC 5 V and DC 24 V operating voltages via the backplane bus. The PS 405 and PS 407 power supply modules also contain the backup batteries for buffering the time and date.

•Supplementary system documentation consisting of a manual for AS 388/TM, AS 488/TM and CS-L2 bridge in German or En- glish.
