Features: 1. C235, C251 high speed pulse input, the function is compatible with FX1N series. Y0, Y1 can send 10K pulse. 2. The power circuit has undergone multiple anti-interference designs, without fear of various harsh electromagnetic interference working environments 3. Can be used flexibly in various industrial automatic control situations, such as metallurgy, chemical industry, printing, central air conditioning, environmental protection equipment. 4. Can also be applied to industrialized control equipment for production machines, industrial assembly lines and various machine tools in industries such as single process control devices. 5. Working voltage is DC24V, output frequency is 10 (kHz), input points are 12 points, output points are 8 points. Specifications: Item Type: Programmable Controller PLC Material: plastic Model: FX1N-20MT Operating voltage: DC24 (V) Output frequency: 10 (kHz) Input points: 12 points Output points: 8 points Input and analog output: 1AD Memory capacity: 2000 steps Some customers respond that downloading programs is slow. The length of our default downloader is 8000 steps. In fact, most clients write programs that don't exceed 2000 steps. Therefore, you can configure it in programming software to increase download speed by 4 times. The setting method is as follows: After clicking the + sign in front of the parameter in the program data list, the PLC parameter will appear, then double-click the PLC parameter and the parameter setting interface will appear. In the setting interface, set the memory capacity from 8000 to 2000. The USB to TTL programming line and USB to 232 driver are the same. After installing the driver, a serial port will appear. Please select a baud rate of 9600 when downloading. This series of PLC has 2 independent 232 serial ports, one is a 9 pin port with 232 level (2: TXD 3: RXD 5: GND) The other is a 4 pin level TTL port (1: GXD 2: TXD 3: RXD 4: 5V), both programmable and connected to the touch screen. When programming, the 9 pin port uses the USB-232 cable; the 4-pin port uses the USB-TTL cable. When connecting the touch screen, the 232 level 9 pin port is directly connected to the touch screen with a 9 pin male to female wire (actually only 3 wires are used, namely 2-2, 3-3, 5-5). The 4 pin level TTL port needs to use our company's TTL to 232 conversion board to convert to the 232 level before it can be connected to the touch screen Size: approx. 73mm/2.9in 58mm/2.3in 66mm/2.6in 65mm/2.6in 30mm/1.2in Package List: 1 x Programmable Controller PLC
