PLC Control Board Programmable Controller Relay Delay Module with Analog FX1N‑32MR DC10‑28V Item Type: PLC Control Board Material: Plastic Model: FX1N-32MR Working Voltage: DC10-28 (V) Output Frequency: 10 (kHz) Maximum Memory Capacity: 8000 Steps Relay Life: 100000 Times The downloading program is slow. The length of the downloading program is 8000 steps by default. Actually, the program written by most customers will 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 232 level 9pin port (2: TXD 3: RXD 5: GND), the other is TTL Level 4pin Port (1: GXD 2: TXD 3: RXD 4 : 5V), both of these ports 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 e our company's TTL to 232 conversion board to convert to 232 level before it can be connected to the touch screen.Size: Approx. 122mm / 4.8in, 87mm / 3.4in, 28mm / 1.1in
