Description

AC Socket is an enhanced AC socket. It supports custom RS485 communication, allowing multiple AC sockets to be connected in series on the same RS485 bus. Through serial communication, multiple AC sockets can be controlled simultaneously, making it suitable for general industrial applications.

Features

• RS485 interface
• Serial communication protocol: ModBUS-RTU
• Supports multiple devices connected in series
• Built-in STM32F030F4
• Uses BASE26 base
• Embedded 4x M3 nuts
• Input: 100-240V
• Output: 10A
• Power status indicator

Includes

• 1x AC Socket

Applications

• Smart AC socket

Specifications

Learn

The AC Socket is constructed by combining the socket panel with the BASE26 base. The base has a 3-pin interface embedded on the side, which serves as the power input for the AC socket.

• The top is the AC plug interface, where the internal relay controls the power on and off.

• To allow more AC sockets to be connected in series, the other side of the socket provides an HT3.96 terminal connector (orange terminal in the image).

• The bottom circuit board is responsible for converting AC power 220V to DC 5V, supplying power to the microcontroller STM32F030F4 and the RS485 circuit. As shown in the image, these two parts are connected via an M-Bus socket and a pair of power lines. A red LED indicator is provided at the top of the socket.

Protocol

ACSocket Modbus RTU Protocol

Description:

• 1. Communication uses RS485, with 1 start bit + 8 data bits + 1 stop bit
• 2. Baud rate: 9600
• 3. Device ID defaults to AAH
• 4. Address 00H is the broadcast address, with no response from the slave

Commands: (Hexadecimal) (Modbus RTU format)

1. Write Coil

Host sends:

AA 05 00 00 FF 00 95 E1 (Close coil)

AA 05 00 00 00 00 D4 11 (Open coil)

Slave response:

Operation successful returns original data:

AA 05 00 00 FF 00 95 E1

Operation failed returns:

AA 85 Error Code CRC_L CRC_H

2. Read Coil

Host sends:

AA 01 00 00 00 01 E4 11

Slave response:

Operation successful returns:

Coil status: 01H -> Coil closed / 00H -> Coil open

Operation failed returns: AA 81 Error Code CRC_L CRC_H

3. Write Device Address

Host sends:

AA 41 00 00 00 12 A4 13

Slave response:

Operation successful returns original data:

AA 41 00 00 00 12 A4 13

Operation failed returns:

AA C1 Error Code CRC_L CRC_H

4. Broadcast Restore Device Address

Host sends:

00 42 00 00 A0 30

Slave response: None
