About this area
How to choose
- Function first: supervision, timing, signal isolation, safety or power switching each point to a different family.
- Coil or supply voltage: match the control voltage, such as 24 V DC or 24-240 V AC/DC universal supply.
- Contact arrangement and rating: count the changeover (C/O) contacts needed and check the switched current at the load voltage.
- Mounting: DIN rail modules, plug-in relays with sockets or panel-mount solid state units.
- Safety duty: for emergency stop circuits, check the required category and performance level before comparing prices.
Frequently asked
What is the difference between an interface relay and a monitoring relay?
An interface relay isolates and amplifies a control signal, for example a PLC output driving a larger load. A monitoring relay supervises a quantity such as phase sequence, voltage or level and switches when it leaves its set window.
Can a relay replace a contactor?
Only for small loads. Relays switch low currents on control circuits, while contactors under IEC 60947-4-1 are rated for motor and power loads. Solid state relays are an option for fast resistive switching.
Do you export relays outside Turkey?
Stoklink ships worldwide from Turkey, EXW. Lead time depends on distributor stock, and project quantities are quoted on request.
