PLC CPUs, safety PLCs and logic modules from Siemens, Schneider Electric and ABB. The range has over 240 controllers, from small logic relays such as LOGO! 8 and Zelio Logic to SIMATIC S7-1500 and redundant S7-400H systems. Stoklink ships worldwide from Turkey and quotes project volumes on request.
What's in this range
- SIMATIC S7-1500 and S7-1500F CPUs, including fail-safe and technology versions.
- SIMATIC S7-1200 and S7-400 CPUs, including S7-400H redundant systems.
- Modicon M221, M241 and M262 controllers from Schneider Electric.
- Logic modules: LOGO! 8 and Zelio Logic for small machines and building control.
How to choose
- Program memory and cycle time: size them to the control task and expected growth.
- Onboard I/O and expansion: small controllers have fixed I/O, larger CPUs scale through modules.
- Interfaces: check PROFINET, Ethernet, serial and OPC UA support against the plant network.
- Safety rating: a safety PLC must match the SIL required by the risk assessment.
FAQ
Can I replace an S7-300 CPU with an S7-1500?
Not as a direct swap. The hardware differs and the program must be migrated in TIA Portal. Plan for new I/O or an interface module.
What does the F in S7-1500F mean?
It marks a fail-safe CPU. It runs safety functions alongside the standard program and needs F-rated I/O for safety signals.
Do you ship CPUs outside Turkey?
Stoklink ships worldwide from Turkey under EXW terms. Lead time depends on distributor stock, and project quantities are quoted on request.
