What's in this range
- PLC power supply modules: PS405 for S7-400, PM 1207 for S7-1200 and Modicon X80 supplies.

- Sync cables for S7-1500H and terminating connectors for S7-400 interface modules.
- Battery boards and backup batteries for real-time clock retention.
How to choose
- Output current: total the draw of CPU and modules, then add margin.
- Input voltage: 24 V DC or 120/230 V AC input must match the control cabinet supply.
- 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
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.
