FX1N-20MR1AD(0-10V)1DA(0-3.3V) PLC Programmable Logic Controller

The FX1N-20MR1AD1DA is a programmable logic controller (PLC) industrial control board with specific features and capabilities. Here’s a summary of its key specifications and functions:

1. Dual Serial Ports: The PLC board is equipped with two independent serial ports for communication. It includes an RS232 level 9-pin port and a TTL level 4-pin port. These ports allow for programming and connecting to a touch screen.
2. RS232 Level 9-Pin Port: The 9-pin RS232 port includes pins for TXD, RXD, and GND. It is commonly used for programming and communication purposes.
3. TTL Level 4-Pin Port: The 4-pin TTL port includes pins for GXD, TXD, RXD, and 5V. It can be used for specific communication needs, but for connecting to a touch screen, it requires a TTL to RS232 conversion board.
4. USB Cable Usage: When programming, a USB-RS232 cable can be used for the 9-pin port, and a USB-TTL cable can be used for the 4-pin port. These cables facilitate programming and communication with external devices.
5. Touch Screen Connection: To connect the touch screen, the RS232-level 9-pin port is directly linked to the touch screen using a 9-pin male-to-female wire. Only three wires are needed for this connection: pins 2-2, 3-3, and 5-5.
6. High-Speed Pulse Inputs: The PLC supports high-speed pulse inputs on specific input points, including C235, C238, C251, and C253. The functionality of these inputs is compatible with the FX1N series.
7. High-Speed Pulse Outputs: The PLC allows for high-speed pulse outputs on output points Y0 and Y1, supporting a pulse rate of up to 10,000 pulses. This functionality is also compatible with the FX1N series.
