Product Description

The FD-L21W sensor module is a versatile industrial detector designed for precision monitoring, featuring dual analog inputs and one digital output for direct integration with control systems. It supports RS-485 communication and operates within 10-30V DC, ensuring compatibility across industrial environments. The FD-L21W temperature controller excels in thermal regulation with ±0.5°C accuracy, functioning reliably between -20°C to 70°C ambient temperatures. Its compact housing (120x80mm screen-less design) suits automation, energy management, and process industries. The FD-L21W industrial detector offers non-contact infrared sensing up to 5m range, with optional 5000mAh backup battery for uninterrupted operation. While optimized for harsh conditions, its configuration requires specialized expertise. This modular solution combines robust performance with low power consumption, ideal for predictive maintenance and real-time monitoring applications.
