Multi-channel relay control PCBA

Number of layers:

Double-layer board

Board size:

Approximately 180mm x 110mm (visual inspection, it is recommended to use a caliper to confirm)

Surface treatment:

Hot air leveling (HASL)

Base material:

FR-4

Assembly type:

SMT patch + DIP plug-in

Product features:

1. Multi-channel relay control function:

Onboard multiple relay modules (blue relays) for controlling high-voltage devices or loads. Each relay corresponds to a channel and can be controlled independently.

2. DIP code setting:

Each control unit is equipped with a 6-bit DIP switch (red DIP) to facilitate setting the address, working mode or device number, suitable for multi-channel or bus system configuration.

3. Multiple input/output interfaces:

With a rich white socket interface, it supports multiple input and output connections, and can expand buttons, sensors or signal lines for easy system integration.

4. Power management and protection:

Equipped with multiple rectifier bridges (marked as 1A 250V), large electrolytic capacitors, inductors and fuses, etc., supporting 24V input and overcurrent protection.

5. Status indication and debugging:

Each circuit module has multiple LED status indicators to facilitate observation of relay action and channel status, and also has RST button and SWD debugging interface.

Applicable scenarios:

Industrial automation equipment control board

Multi-channel output relay module (such as building control, lighting control)

Smart home central control module

Security system multi-point control unit

IoT gateway/terminal relay execution module
