Why local automation supply changes project outcomes
Delivering automation on time in South Africa means more than buying parts online. It requires reliable local stock, clear specification guidance, and procurement support that understands lead times, VAT invoicing and branch collection. Communica holds deep ranges of PLC modules, I/O, industrial relays, sensors and cabling so you can avoid multi-week delays and keep commissioning windows intact.
What you gain working with Communica
- Immediate visibility of in-branch stock and same-day pickup from Samrand, Pretoria CBD or Cape Town.
- Practical compatibility advice and accessory bundles (power supplies, terminal blocks, gland kits) to turn components into install-ready assemblies.
- Account quoting, VAT-compliant invoices and support for education/tertiary procurement processes.
Quick specification callouts - match parts to the role
Before you buy, check four practical specs that break project risk: supply voltage range, IO signal type (sourcing/sinking / NPN/PNP), switching current and enclosure rating for your site. Below is a compact spec comparison you can use to narrow picks quickly.
| Component | Key spec to verify | Typical Communica categories |
|---|---|---|
| PLC CPU | Supply 24 VDC, program memory, Ethernet ports | Collections: PLC & Controllers |
| Digital I/O module | IO type (sourcing/sinking), channel current, isolation | Collections: All Products |
| Industrial sensor | Sensing range, output type (PNP/NPN, analog 4-20mA) | Collections: Sensors & Transducers |
Compatibility guidance and accessory bundles
We bundle the small items that commonly cause site hold-ups: DIN-rail power supplies sized with 25% headroom, terminal blocks and cable glands matched to the cable diameter, and shielded patch leads for Ethernet-connected controllers. Ask for a prebuilt bundle with a mounting panel so procurement gets a single line item and commissioning teams get everything they need.
