About this Gig
High-voltage spikes, ground loops, lightning surges, and heavy motor noise will destroy unshielded communications instantly.
I engineer ultra-rugged, galvanic-isolated RS485 and Modbus communication PCBs designed to survive the harshest industrial conditions. Whether for factory automation, solar arrays, or heavy machinery telemetry, my designs ensure uninterrupted uptime.
My Industrial Design Blueprint Includes:
True Galvanic Isolation: Total split-plane isolation separating sensitive MCUs from field wiring using premium optocouplers or digital isolators.
Triple-Stage Surge Protection: Integrated Gas Discharge Tubes GDTs, Transient Voltage Suppressors TVS, and PPTC resettable fuses.
Isolated Power Networks: High-efficiency isolated DC-DC converter blocks to supply clean power across the isolation barrier.
Robust Field Connectivity: Fail-safe biasing, terminal blocks, and optimized impedance termination networks.
What You Will Receive:
Industry-grade schematic designs and high-reliability PCB layouts.
Manufacturing package: Gerbers, NC Drills, BOM, and Pick-and-Place files.
3D STEP models for enclosure fitment testing.

FAQ
Can this design handle Modbus RTU protocols?
Yes. RS485 is the physical layer, and I design the hardware to cleanly support Modbus RTU, Profibus, or any custom serial data protocol running over differential lines.
What voltage levels of isolation do your designs support?
I standardly design for 2.5kV to 5kV RMS galvanic isolation, depending on your specific operating environment and industrial safety standards.
