USB-C Wi-Fi/BLE Sensor Design
Design a control panel schematic for a Boric Acid Slurry Automatic Measurement System. Please represent the PLC and external devices using terminal headers or generic IC blocks if specific parts are unavailable. Add text notes for wire colors: Black(AC L), Blue(AC N / DC 0V), Red(DC +24V), Yellow(Signals).
- Power Supply:
- Add a 220V AC input block.
- Add an AC/DC SMPS (220V AC to 24V DC).
- Inputs (24V DC, Source Input logic):
- Create 4 input paths powered by +24V.
- X0: Connected via a Normally Open (NO) Pushbutton (Start).
- X1: Connected via a NO Pushbutton (Stop).
- X2: Connected via a NO Relay contact (representing Temp Controller 40°C).
- X3: Connected via a NO Relay contact (representing Temp Controller 43°C).
- Route all inputs to a generic block representing 'PLC Inputs'.
- Outputs (24V DC, Sink Output logic - switching to GND):
- Create a block representing 'PLC Outputs' (Y0 to Y3).
- Y0: Connect to the negative control input of an SSR. The load side of this SSR switches 220V AC for 'P-101 Pump'.
- Y1: Connect to the negative coil of a standard DC Relay. The NO contact of this relay switches +24V DC for 'P-102 DC Pump'.
- Y2: Connect to the negative control input of an SSR. The load side switches 220V AC for 'V-1 Main Pump'.
- Y3: Connect to the negative coil of a DC Relay for an Alarm.
- Communication:
- Add an RS-485 transceiver or a generic 2-pin header labeled 'RS-485 RDA/RDB for Turbidity Sensor'.
Thought
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.
Worked
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.
