6 input, 4 point open collector outputWide supply voltage 10-28VDCDimensions: length X width X high:36X73X20Mm This board is PLCboard, the direct use of GX programming software ladder diagram, written directly to the PLC, you can monitor online, even cheaper than the microcontroller board. Advantages of using PLC boards:1 programming convenience, customers can learn to learn a day2 reusable3 high stability4 easy to expand The history of the smallest volume, the cheapest display and display panel input parameters, functions as a touch screen, touch screen is another advantage compared to the greater is the board without programming, digital display and input parameters can be fitted. 1 a power will always show the value of the data register D0 mode, the user can be used in the PLC ladder diagram MOV D D0 command to change the value of D0 can display the value of different data registers.2 when you press the MODE button for 3 seconds on the left of the decimal point will light up into the adjustment data register number model, then through the two buttons on the right side of the increase or decrease the value, to adjust to adjust the data register number, such as D128 will be set to 100 in the pace of 128.3 press the MODE button 3 seconds on the right side of the decimal point will light up into the adjustment step of the selected data register value model, the same through the two buttons on the right side of the increase or decrease the value, to adjust the data register values, such as D128 will be set to 100, in this step 1004 when pressing the MODE key for 3 seconds, then enter the value pattern of the data register D0.The latest additions are as follows:The data register has been displayed in the D0, D2 value mode, can be displayed on the board after the MODEThree buttonsUP, DOWN, RST control 3 intermediate relay M, corresponding to the following:RST key press, M173 conductionRST key release, M173 disconnectDOWN key press, M172 conductionDOWN key release, M172 disconnectUP key press, M171 conductionUP key release, M171 disconnect Equivalent to an increase of 3 buttons, you can use the display board on the 3 buttons used when the button is used, such as the UP key used to run the motor DOWN is used to stop the motor running RST used to count cleared.
