1、No external power supply is required, and power can be supplied directly from the S8 programming communication port of the PLC. 2、Expand one RS422 programming port of PLC into two programming ports, and the communication speed is basically the same as the original programming port. 3、No need to set up, plug and play, easy to use, small in size, but take up more installation space. 4、Automatically adjust the baud rate of the FX programming communication port to meet the needs of large data communication. 5、Widely used in the signal acquisition and control of industrial field equipment. Item Type: Expansion Module Material: Aluminum alloy Model: FX-2T1 Indicator Lights: PWR, SYS, PLC, COM1, COM2 five indicators Protocol Support: MELSOFT, for Mitsubishi programming port protocol Applicable Models: FX1S, FX1N/1NC, FX2N/2NC, FX3U/3UC, FX3G/3GA/3GC, FX3S Interface Type: MD8 communication female port Transmission Rate: Default 9.6K, baud rate adaptive Power Supply Mode: FX series PLC communication port (connected with communication cable) to take power directly or 9~28VDC power terminal FX-2T1 module is an economical for Mitsubishi FX series PLC programming port expansion module, which realizes the expansion of one RS422 programming port  for Mitsubishi FX series to two. When the PLC programming port is occupied, it has already communicated with a device. At the same time, it is convenient for the user to monitor and debug the programming software, or add another RS422 serial device to communicate with the PLC.Size: Approx. 83mm / 3.3in 60mm / 2.4in 5mm / 0.2in 9mm / 0.4in 13mm / 0.5in 10mm / 0.4in 11mm / 0.4in 16mm / 0.6in 25mm / 1in 14mm / 0.6in 8mm / 0.3in 1 x Expansion Module 1 x Connection Line
