USB-C Wi-Fi/BLE Sensor Design

I’ll add a separate control-panel schematic block for the boric acid slurry measurement system, using terminal headers/generic blocks for the PLC, SMPS, SSRs, relays, pumps, alarm, and RS‑485 sensor wiring. I’ll keep the existing design intact unless you explicitly ask me to replace it.
Added the Boric Acid Slurry control-panel schematic as a separate subsystem without removing the existing sensor-node design.
Completed:
  • 220 VAC input and 220 VAC → 24 VDC SMPS.
  • PLC input block with X0 Start, X1 Stop, X2 Temp 40 °C, X3 Temp 43 °C using +24 V source-input logic.
  • PLC output block with Y0–Y3 sink-output logic for SSRs/relays, P-101, P-102, V-1, and alarm.
  • RS-485 RDA/RDB terminal for turbidity sensor.
  • Wire-color notes documented in the project file: Boric Acid Slurry Automatic Measurement System — Control Panel Wiring.
Electrical review for the new control-panel wiring returned no matching ERC errors/warnings. Note: final SSR/relay/contact ratings should be checked against real pump current, inrush, enclosure, fusing, and local electrical safety requirements before panel build.
