The Dataie DTD435M wireless communication module offers RS232/RS485 interfaces, supports N:N and Modbus protocols, and provides up to 3000 m range.
The DTD435M is an industrial‑grade wireless data terminal designed for PLC networks. It replaces traditional wired RS232/RS485 connections, enabling wireless download, debugging, and operation across multiple PLCs. The module features a compact aluminum housing (120 × 105 × 30 mm) with four mounting holes and operates on a wide DC supply range of 9‑24 V.
It supports several serial protocols, including Nbdbus, N:N, Modbus, and specific PLC programming protocols, and can communicate with devices such as Siemens, Huayi, and other PLC brands. Various model variants provide different maximum wireless distances, ranging from over 60 m to approximately 3000 m, making it suitable for short‑ to medium‑range industrial monitoring and control applications.
