Features: This programmable logic controller uses industrial-grade 32-bit MCU with strong anti-interference and faster speed. Program is written in ladder logic programming language, supports for GX-Developer, GX-work2, supports HMI connection. Support ladder logic programming language programming, downloading and monitoring. Programming port is the port for program upload, download and HMI communication. Comes with a cable for convenient connection. Specification: Model FX3U-24MR DC24V Program Steps 8000 steps:2 communication port:one RS232 (DB9 serial communication port is FX3u, one RS485 (485 choose match) (communication protocol can be set D8120) Input Point X Component X0-X15, DC24 input, low level effectively.X0-5 high-speed counting input port (default is 12 KHZ).
