TX1N-485-BD-4 is an RS485 serial communication expansion board with 1 channel and 4-wire connection.

This board can be used to expand the RS485 interface in LX1S/LX1N/LX2N series PLCs. The RS485 interface provides high-speed and reliable communication, and the board can be used to configure multidrop, parallel link, or peer-to-peer networks.

The communication speed of the board can vary between 300-19,200 bits/s. Additionally, the board supports multiple protocols and can be used in various network configurations.

The board is connected directly to the communication bus on the left side of the PLC. The board uses a 4-wire connection, and the cable on the communication line must be correctly configured and connected.

Overall, TX1N-485-BD-4 is an expansion board used for RS485 serial communication. It provides faster and more reliable data transfer and communication between devices.

Editor notes: "Dear friends, this module and its supported PLC models have now been replaced by newer models. If you are starting an automation project from scratch, we recommend that you choose our newer models instead. Thank you for your understanding!"
