🧠 Tips When Buying PLC & SCADA Modules

✔ Always confirm part numbers (e.g., Siemens 6ES7 series)
✔ Check compatibility with existing systems
✔ Verify voltage and communication protocols
✔ Avoid mixing incompatible PLC families
✔ Choose trusted brands used in SA (Siemens, ABB, etc.)
✔ Consider lead times and availability
✔ Ask for warranty (6–12 months typical)
✔ Use suppliers who understand Eskom / Transnet standards

👉 Pro Tip:
Digital and analog I/O modules are the fastest-moving spares — keep stock.
