Product Description

The TB-4M8M-3N2-5 industrial control module features integrated TB-4M8M connectors supporting 4 digital inputs and 8 digital outputs, enabling direct connectivity with up to six peripheral modules. It incorporates 3N2 relay terminals for robust switching capabilities and integrates 5A power modules for stable current handling. Designed for harsh environments, it operates within a 12-24V DC range and withstands temperatures from -20°C to 70°C. Equipped with RS-485 and CAN interfaces, it is widely used in automation, manufacturing, and energy systems. Advantages include high reliability, modular expandability, and compatibility with diverse sensors (detection range up to 15m). Limitations include a compact design requiring external cooling for sustained high loads. Suitable for applications demanding precision control and scalable industrial networking.
