MAX485 control relay module with hexadecimal coding, convenient and compact for computer control via RS485, DC7-30V supply voltage.

Welcome to our shop! Discover our RS485 computer-controlled relay module, a versatile and efficient tool for your automation projects. Designed for a wide DC voltage range, it works perfectly with input voltages from DC7V to DC30V, offering great flexibility for integration into various systems. At the heart of its reliability is the MAX485 communication IC, an imported component that guarantees smooth and stable data exchange. It uses the standard communication format (9600, 8, NONE, 1) for optimal compatibility. Its operation is simple and powerful. Using a serial port wizard, you can control the relay's state by sending precise hexadecimal commands: send **01AAFF** to open (activate) the relay, **01BBFF** to close (deactivate) it, and **01CCFF** for a pulse (jog mode). Its design is a major advantage. With a compact plastic housing measuring just **77.8 x 47.5 x 18.8 mm (approximately 3.1 x 1.9 x 0.7 inches)**, it is both small and robust. This small size allows it to be easily integrated without taking up valuable space, whether for storage or installation in your assemblies. Installation and commissioning are remarkably simple. No complicated processes are required to start using this high-performance relay module. **Product Details:** **Item Type:** RS485 Computer-Controlled Relay Module** **Model:** YF 9** **Material:** Plastic** **Product Size:** Approx. 77.8 x 47.5 x 18.8 mm / 3.1 x 1.9 x 0.7 inches** **Supply Voltage:** DC7V to DC30V (Wide Voltage)** **Communication Chip:** MAX485 (Imported Chip)** **Communication Format:** 9600 baud, 8 data bits, no parity, 1 stop bit** **Control Protocol:** Hexadecimal encoding via serial port (01AAFF=OPEN, 01BBFF=CLOSED, 01CCFF=PULSE)** Your order includes:*** 1 x Computer-Controlled Relay Module RS485
