Features 1.Input high‑speed pulse C235, C251, the function is compatible with FX1N series. Y0, Y1 can send 10K pulse. 2.The power circuit has undergone multiple anti‑interference design, without fear of various harsh electromagnetic interference working environments 3.Can be flexibly used 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 machinery, industrial assembly lines, and various machine tools in industries such as single process control devices. 5.The working voltage is DC24V, output frequency is 10 (kHz), input points are 12 points, Output Points are 8 points. Specification Item Type: Programmable Controller PLC Material: Plastic Model: FX1N-20MT Working Voltage: DC24 (V) Output Frequency: 10 (kHz) Input Points: 12 points Output Points: 8 points Analog Input and Output: 1AD Memory Capacity: 2000 steps Some customers respond that downloading programs is slow. Our default download program length is 8000 steps. Actually, most customers write programs that do not exceed 2000 steps. Therefore, you can set it in the programming software to increase the 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, and then double-click the PLC parameter and the parameter setting interface will appear. In the parameter setting interface, set the memory capacity from 8000 to 2000. The programming line USB to TTL 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 PLC Series Has 2 Independent 232 Serial Ports, One Is a 9pin port with 232 level (2: TXD 3: RXD 5: GND) The Other Is A TTL Level 4pin Port (1: GXD 2: TXD 3: RXD 4: 5V), both of which are programmable and connected to the touch screen. When programming, the 9pin port uses the USB-232 cable; the 4pin port uses the USB-TTL cable. When connecting the touch screen, the 232 level 9pin port is directly connected to the touch screen with a 9pin male to female wire (actually only 3 wires are used, namely 2-2, 3-3, 5-5). The TTL level 4pin port needs to use our company's TTL to 232 conversion board to convert to 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
