Product Description

The NS485I8-J module is an industrial-grade RS485 I/O module designed for robust data acquisition and control applications. It features 8 digital inputs and 8 relay outputs, enabling direct integration with sensors, actuators, and peripheral devices. The NS485I8-J interface supports RS485 communication with a maximum range of 1,200 meters, compatible with Modbus RTU protocol for seamless network connectivity. It operates within a wide voltage range of 9-36V DC and functions reliably in temperatures from -25°C to +75°C. Ideal for automation, energy management, and HVAC systems, this module allows daisy-chaining of up to 32 units on a single bus. Key advantages include high noise immunity, DIN-rail mounting, and galvanic isolation, while its lack of built-in display or wireless connectivity may limit certain applications. The compact design (80mm x 60mm x 25mm) ensures space-efficient deployment in control cabinets.
