Hardware Design Description
1)Input Power Requirements
| Min | Type | Max | Unit | |
| 3.3Vin | 3.0 | 3.3 | 3.6 | V |
- Place at least one 10uF, 0.1uF ground energy storage capacitor near the 3.3V input of the module on the mainboard to reduce the power ripple. The peak-to-peak value of the ripple is within 100mVpp.
- The module 3.3V is isolated from other 3.3V on the mainboard by using 600R/100MHz, 1A or more ferrite beads.
- The module 3.3V circuit guarantees at least 200mA or more current requirements.
2)PLC Module Docking Whole Machine Design
For the overall product design, the safety protection design on the L/N line, and the PLC signal coupling design, it is strongly recommended to refer to the following circuit diagram and material selection.
Note: In the figure, the T1 transformer is a 1:1 transformer; the C1 safety capacitor is recommended to be a 10nF safety capacitor; the primary and secondary bidirectional TVS protection tube (D1/D2) is required; the PLC signal access point on the L/N line needs to be behind the varistor (RV1), and the varistor junction capacitance is recommended to be less than 600pF. Two differential mode inductors (L1/L2) need to be connected in series behind the PLC signal to isolate it from the power supply of the whole machine, and the differential mode inductor value is recommended to be 50~100uH.
3)CCO and STA Typical Networking Diagram
- CCO is the PLC centralized controller, and STA is the PLC station.
- CCO and STA have the same hardware but different software.
- In simple applications, CCO can be networked independently without an external MCU. Networking that requires cloud access requires an external MCU to be implemented through wired Ethernet or wireless.
- In a typical CCO networking environment, it is recommended to add an AC220 isolator to the 220VAC line at the front end of the CCO to filter out noise from other power networks to avoid affecting the local CCO network communication quality. This also reduces the interference of the local CCO on other PLC communication networks.
