Relays and monitoring devices from ABB, Siemens and Schneider Electric for industrial control panels and automation. The range covers monitoring, timer, interface, safety, latching and solid state relays, plus sockets, with ratings from fractions of an amp up to 125 A. Stoklink ships worldwide from Turkey and quotes project volumes on request.
What's in this range
- Monitoring Relays (Phase, Voltage, Current, Level) – phase, voltage, current, residual current and level supervision.
- Timer Relays – on-delay, off-delay, flasher, multifunction and star-delta timing.
- Interface & Plug-in Relays – miniature plug-in relays for PLC outputs and control circuits.
- Safety Relays – emergency stop and guard monitoring modules.
- Switching, Latching & Impulse Relays – DIN rail interface, latching and impulse switching.
- Solid State Relays – contactless AC switching with no moving parts.
- Relay Sockets & Accessories – sockets, jumper bars and related accessories.
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.
FAQ
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.
