About this Gig
I design professional relay-based control systems using Schneider Zelio programmable relays (SR2 / SR3 series) and standard wired logic. This service is ideal when a full PLC is unnecessary and a reliable, cost-effective solution is needed.
I specialize in:
- motor starters (direct, reverse, star-delta)
- pump control (level, pressure, alternating, duplex systems)
- ventilation, HVAC & fans
- compressors, valves, solenoids
- lighting and access automation
- safety interlocks, latching, alarms, timers, counters
What I deliver:
- relay logic design (Function Blocks Diagram)
- Schneider Zelio Soft project file
- wiring diagrams in QElectroTech (PDF + source)
- component selection & BOM (Schneider compatible)
- installation & wiring instructions
Why Zelio:
- simple programming
- low cost hardware
- suitable for small machinery and panel retrofit
- reliable for industrial and building automation
I focus on practical, compact, low-voltage control solutions with clear documentation and clean schematics. Just text me and let's strat it!

FAQ
Revisions
⚠ Revisions cover adjustments within the original scope of work. If new features or changes are requested, I’ll be happy to send a custom offer.
Can you work with Siemens, Omron, Mitsubishi or other PLCs?
No. I specialize exclusively in Schneider Zelio SR2/SR3 and relay-based control systems, not full PLC platforms.
Can you help choose components?
Yes. I can provide a BOM with Schneider-compatible relays, terminals, breakers, contactors, etc.
