One, Product Overview
This product is an intelligent conversion module that converts dry contact signals into custom bus data. It supports opening and closingdisconnect, , opening and closing, closing and opening, flipping states, single clicking, double clicking, , long pressing, and continuous pressingactions through dry contact switches to send multiple sets of custom commands and control third-party devices (such as lighting, sensors, fans, valves, etc.), achieving personalized scene linkage. Suitable for home decoration, workwear, municipal, industrial, agricultural and other scenarios, supporting RS485 bus communication and multiple extension protocols (requiring conversion modules).
II. Product Features
- Compact Design: Size 46 × 57mm, can be embedded into an 86 bottom box.
- Stable and reliable: Each input optocoupler is isolated, with strong anti-interference ability, and supports weak current signal transmission over a 300 meter Ethernet cable.
- Flexible Configuration:
- supports address modification and baud rate customization (1200-115200bps).
- Each switch supports sending 4 sets of custom data (on/off/click/double-click).
- Supports delay control of 0.1-399 seconds.
- Bidirectional Communication: Interface status can be queried, and local control can still be achieved even when the network is disconnected.
- Security ProtectionSupport button locking (single or global) to prevent accidental touches.
- Strong scalabilityCan connect to protocols such as KNX, CAN, LoRa, WiFi, etc. (requires conversion module).
- Baud rate: configurable
- Parity verification: configurable
- Data bits: configurable
- Stop position: configurable
- Multiple message sequence delayed delivery: support

VII. Precautions
- Do not exceed 12V power supply voltage to avoid damaging the module.
- The RS485 bus needs to use shielded twisted pair, and the terminal equipment should be equipped with a 120 Ω resistor.
- It is recommended to test signal stability during long-distance transmission. When modifying the address, ensure that there are no conflicts on the bus. After the lock function is enabled, an unlock command needs to be sent to restore the operation.
- Ensure that there are no conflicts on the bus when modifying the address.
- After the locking function is enabled, an unlock command must be sent to restore the operation.
