Dear EhrenMitglied, You can use the S7-400 power supplies4Amp or 10 Amp for redundant system. The only parameter you have to consider is the current consumption limit. First note that the 4Amps and 10 Amps are the output current at 5VDC. So you can sum the current consumption of all the modules (at 5VDC) including the CPU and then you have to see if these modules needs 10 A or 4 A at 5VDC. And keep in mind that the PS 10A takes two slots in S7-400 rack. [schnippschnapp] Regards, |
