Product Description

The NS301I I/O module integrates 8 digital inputs and 8 relay outputs, designed for seamless integration with the NS301I PLC controller in industrial automation systems. This compact NS301I relay module supports up to 32 expansion modules via Ethernet, RS-485, or Modbus interfaces, ensuring scalable connectivity. Operating within 12-36V DC and a temperature range of -20°C to 60°C, it excels in harsh environments like manufacturing and building management. Key advantages include high reliability, plug-and-play installation, and a built-in 2000mAh backup battery for power continuity. However, it lacks analog input support. With a sensor detection range of up to 20 meters, the NS301I series offers efficient control solutions despite limited customization options for complex protocols.
