- Dimensions: 40mm × 160mm × 50mm (W×H×D); Mounting: Standard 35mm DIN rail mounting, compact design.
- Functional Features:
- Standard RS-232C communication interface with DB9 female connector is fully compatible with various RS-232 standard peripheral equipment, with a screw locking structure to ensure firm connection and prevent signal disconnection caused by industrial site vibration.
- Wide range of configurable transmission rates (300 bps-115200 bps) and flexible data format settings adapt to different RS-232 equipment communication requirements, with strong compatibility and adaptability.
- Support multiple communication protocols (Modbus RTU, Modicon dedicated programming protocol, transparent transmission), software configurable, which can realize PLC programming, data communication with HMI and transparent data transmission with various RS-232 industrial equipment, with rich communication functions.
- 2500 VAC high-voltage electrical isolation between the module and PLC backplane bus effectively isolates the electromagnetic interference of the RS-232 communication line on the PLC system, preventing interference signals from entering the PLC backplane bus and ensuring the stable operation of the PLC system.
- Industrial-grade anti-interference design with built-in surge protection and signal filtering circuit on the communication interface, which can suppress the surge and interference on the RS-232 communication line, ensuring stable and reliable serial communication in harsh industrial field environments.
- Transparent transmission function allows the PLC to exchange data with RS-232 equipment without protocol conversion, simplifying the PLC program design and facilitating the connection with non-standard RS-232 industrial equipment.
- LED status indicators for power on (green), communication link (yellow) and data transmission (red) realize visual monitoring of the module working status and communication process, facilitating quick troubleshooting of serial communication faults.
- Compact narrow width design saves the installation space of the industrial control cabinet, and the standard DIN rail mounting design is convenient for on-site installation and disassembly, suitable for dense installation with other PLC modules.
- Low power consumption design does not increase the overall power load of the PLC system, and the power supply from the PLC backplane bus eliminates the need for additional power supply wiring, simplifying the system wiring structure.
- Fully compatible with AEG Modicon 800/900/984 series PLC systems, plug-and-play, no additional driver software required, and the communication parameters can be configured online through the PLC programming software, with simple operation.
- Application Scenarios: Widely used for the RS-232 serial communication connection between AEG Modicon PLC systems and various RS-232 peripheral equipment in industrial fields such as factory automation, process control, municipal engineering and intelligent building control systems. It is applied in PLC programming and debugging with handheld programming terminals, data communication between PLC and RS-232 type HMI, data printing with industrial printers, and barcode data collection with barcode scanners, and is suitable for all industrial occasions that require RS-232 serial communication between Modicon PLC systems and peripheral equipment.
