Product Description

The FQ-300D-NH sensor is a high-performance industrial device featuring 4 analog/digital inputs and 2 configurable relay outputs, designed for seamless integration with automation systems. It supports direct connection to up to three FQ300DNH modules for expanded functionality, compatible with FQ series controllers. Communication interfaces include RS-485 and Ethernet for robust data exchange. Operating within a 9-24V DC range and -20°C to 60°C temperature tolerance, it excels in harsh manufacturing, energy, and logistics environments. The sensor offers a 5-inch LCD for real-time monitoring, a 5000mAh backup battery, and a detection range of 0.1 to 10 meters. Key advantages are its rugged build and flexible I/O configuration, though it lacks wireless connectivity. Its compact design ensures reliability in space-constrained installations.
