Platform match: supplies and memory cards are series-specific.
Cable length: sync and interface cables come in fixed lengths, so measure the rack distance.

FAQ

PLC Power Supplies, Memory Cards & Accessories questions

Can I use any 24 V supply for a PLC?

Only if it delivers stable, regulated 24 V DC at the needed current. Platform power modules also feed the backplane, which a generic supply cannot do.

What does a battery board do in an S7-1200?

It keeps the real-time clock running when the CPU has no power, for a limited period.

Do you export small PLC accessories?

Stoklink ships worldwide from Turkey under EXW terms. Lead time depends on distributor stock, and project quantities are quoted on request.
