Product Description

The Mitsubishi QJ71C24 module is a Melsec-Q C24 communication interface designed for serial data exchange in industrial automation systems. It features two independent QJ71C24 serial interface channels supporting RS-232 and RS-422/485 protocols, with baud rates up to 230.4 kbps. The module operates on a 5VDC power supply (tolerance ±5%) and functions within 0-55°C ambient temperatures. Directly compatible with Melsec-Q PLCs, it enables communication with up to 32 connected devices via multidrop networks. Key applications include factory automation, process control, and machine monitoring. Advantages include dual-channel flexibility, protocol versatility (MELSEC, bidirectional protocols), and error detection capabilities. Limitations involve complex parameter configuration via GX Works software and lack of onboard power isolation. This industrial-grade module excludes battery support, display components, and proximity sensing features, prioritizing robust serial communication in demanding environments.
