PLC I/O modules and remote I/O from Siemens, Schneider Electric and ABB. The range has over 600 products, including digital input and output modules, analog modules, fail-safe I/O and bus couplers for SIMATIC ET 200SP, ET 200AL, Modicon TM3 and X80, and ABB S500. Stoklink ships worldwide from Turkey and quotes project volumes on request.
What's in this range
- Digital input and output modules at 24 V DC and 120/230 V AC, including relay outputs.
- Analog input and output modules for current, voltage and temperature signals.
- Fail-safe I/O such as SIMATIC ET 200SP F-DI and ABB AI581-S safety modules.
- Interface modules and bus couplers, for example ET 200SP IM 155-6 and Modicon TM3 EtherNet/IP.
How to choose
- Platform match: I/O modules are specific to their rack or bus, so match the series.
- Signal type: sourcing or sinking, 24 V DC or AC, relay or transistor output, current rating per channel.
- Analog resolution and range: 4-20 mA, 0-10 V or RTD, and 12-bit versus 16-bit.
- Protection class: IP20 for cabinets, IP67 for machine-mounted field I/O.
FAQ
Can I use S7-1200 signal modules with an ET 200SP?
No. ET 200SP uses its own I/O modules and base units. S7-1200 modules only work with S7-1200 CPUs.
What is the difference between a relay and a transistor output module?
Relay outputs switch AC or DC loads with isolation but wear mechanically. Transistor outputs switch DC loads quickly and have no contact wear.
Can I order a full rack of modules?
Stoklink ships worldwide from Turkey under EXW terms. Lead time depends on distributor stock, and project quantities are quoted on request.
