The TX1N-485-BD-2 is an RS485 serial communication expansion board designed for use with the LX1N/LX2N series PLCs. This expansion board provides an additional RS485 interface for the base unit, which allows for the configuration of RS485 1:n multidrop, parallel link or peer-to-peer networks with LX1N/LX2N systems. The board is inserted into the base unit's expansion slot, making it easy to install and use.

With the TX1N-485-BD-2, it is also possible to transfer data directly to other RS485 peripherals using the RS dedicated instruction. In peer-to-peer network configurations, the interface adapter enables active communication between the individual LX1N/LX2N controllers via the RS485 interfaces. This allows for efficient data transfer and communication between multiple devices.

In 1:n multidrop networks, the adapter can be used to provide communication with a host master station of the A series. This allows the LX1N/LX2N PLCs to communicate with other devices on the network and enables integration with other systems.

Overall, the TX1N-485-BD-2 provides a simple and reliable way to expand the communication capabilities of LX1N/LX2N series PLCs. It is a versatile solution for a range of applications that require RS485 communication capabilities.

The TX1N-485-BD-2 RS485 serial communication expansion board is applicable for use with both LX1S/LX1N and LX2N base units. The board conforms to the standards of LX1S/LX1N/LX2N base units and is powered by a 5V DC / 60mA power supply from the base unit.

The communication interface of the board supports both RS485 and RS422 protocols, with a communication speed of 300-19,200 bits/s. The communication cable used is twisted-pair, and the maximum communication distance is 50 meters.

The board supports Protocol 1 or 4 of AJ71UC24, as well as no protocol, parallel link, and peer-to-peer network communication protocols. The related I/O points for the board are Station 0, with 0 points.

The weight of the board is 0.02 kg for LX1S/LX1N base units and 0.08 kg for LX2N base units. The dimensions of the board are 43 x 38.5 x 22 mm for LX1S/LX1N base units and 35 x 54 x 22 mm for LX2N base units.

Editor notes: "Dear friends, this module and its supported PLC models have now been replaced by newer models.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!"
