Information About QJ71C24N
The QJ71C24N is part of Mitsubishi’s MELSEC-Q automation platform, designed to expand controller communication capability through dual serial interfaces. Its construction features a compact form factor with a 27.4 mm width and robust compliance with CE, UL/cUL, EAC, RoHS, and major marine certifications. The module integrates easily into Q-series racks and occupies 32 I/O points per slot, enabling RS-232 point-to-point communication as well as RS-422/485 multi-drop networking. Typical applications include device integration, modem communication, SCADA links, and networking between PLCs and external serial equipment in both industrial plants and marine systems.
Key Features:
- Dual serial ports: One RS-232 port for point-to-point links and one RS-422/485 port for multi-drop networks.
- Asynchronous communication: Supports synchronous and full-duplex serial data exchange.
- Modem support: RS-232 port can operate in modem mode for remote communication.
- Compact module size: Fits easily into dense control cabinets with 27.4 mm width.
- Wide environmental range: Operates from 0 to 55 °C and 5–95% non-condensing humidity.
- Marine approvals: Certified by ABS, BV, DNV-GL, LR, NK, and RINA for shipboard use.
- Industrial certifications: CE, UL/cUL, EAC, and RoHS compliant.
- Robust installation ratings: Shock resistance up to 15 g for demanding environments.
The QJ71C24N delivers the reliability and precision required for stable serial communication within MELSEC-Q automation and marine control systems.
