The A1SJ71QC24N-R2 is a serial communication module manufactured by Mitsubishi Electric. It belongs to the QnA series of serial communication modules, which are designed for use with the QnACPU MELSECNET/10 and Remote I/O station PLCs. The A1SJ71QC24N-R2 module is specifically designed for serial communication and offers two RS-232C ports. These ports provide connectivity for external devices such as modems or terminal adapters (TAs). The module supports both pulse and tone transmission types for flexibility in communication protocols. With this module, users can connect one modem or TA for establishing communication with external devices. It supports a maximum data transmission rate of 115200 bps, enabling high-speed data exchange between the PLC and connected devices. The A1SJ71QC24N-R2 module supports various line connection methods, including the analog 2-line method, analog 4-line method, and digital line (ISDN) method. This makes it compatible with different communication network configurations. The module also supports line disconnection, which means it can be disconnected from the line when not in use to save energy and improve efficiency. Additionally, it supports line connection through dialing, allowing for automatic connection establishment when needed. The A1SJ71QC24N-R2 module supports the nonprocedural protocol and bidirectional protocol. The nonprocedural protocol is a protocol that allows the transmission of data without specific procedures or sequences. The bidirectional protocol enables two-way communication, allowing both the PLC and connected devices to exchange data and commands. Overall, the A1SJ71QC24N-R2 serial communication module by Mitsubishi Electric offers reliable and versatile connectivity options for PLC systems. With its 2 RS-232C ports, support for various line connection methods, and compatibility with different communication protocols, it enables seamless communication between the PLC and external devices.
