Product Description
Universal model Redundant Power Supply Module QJ71C24N-R2 100 to 240 V AC
QJ71C24N-R2 Description
The QJ71C24N-R2 is a high-performance serial communication module designed for integration into modular industrial automation control systems. It serves as a critical interface bridge, enabling seamless data exchange between the main controller and a wide range of external serial devices. This module supports dual independent communication channels, offering flexible configuration for various serial communication standards, and is engineered for reliable, high-speed data transfer in demanding industrial environments.
QJ71C24N-R2 Key Features
- Dual Independent Channels: Features two separate communication channels (CH1 and CH2), each configurable for RS-232, RS-422, or RS-485 standards.
- High-Speed Communication: Supports baud rates from 50bps up to 230.4kbps, with a maximum aggregate speed of 230.4kbps across both channels.
- Multi-Protocol Support: Compatible with MC protocol, predefined protocol, non-procedural (free) protocol, and bidirectional protocol for versatile connectivity.
- Flexible Transmission Control: Supports various control signals including DTR/DSR, RS/CS, CD, and software flow control (Xon/Xoff, DC2/DC4).
- Robust Error Detection: Integrates parity check and checksum functions to ensure data integrity and transmission reliability.
- Remote Access Capability: Equipped with modem support and a remote password function for secure remote programming and monitoring.
- Easy System Integration: Designed for standard modular rack mounting, occupying a single slot with straightforward software configuration.
- Industrial-Grade Reliability: Built to withstand harsh industrial conditions with comprehensive electromagnetic compatibility (EMC) and safety certifications.
