PLC external wiring diagram

The definition of 1/0 of PLC is as shown in the table. There are 13 input signals
, including: 1# motor start button. The normally open contacts of the photoelectric switches of the 2#, 3#,
5#, 7#, 8#, and 9# stations, the upper and lower stroke switches of the 37 and 7' cylinders of the transfer cutting machine, and the spraying completion
signal SF and response Ceramic blank in place signal ARP.
    The PLC output has 18 channels, including: 9 motor control signals for stations 1# to 9#, rising and falling electromagnetic
control signals for cutting machines 3, 7 and 7', and motors for cutting machines 3, 7 and 7'. control signal, clamping electromagnet control signal, ceramic blank in place signal RI, and response to spraying completion
signal ASF.
    The output control signal YO-Y17 does not directly drive the AC contactor or solenoid valve, but is driven through a solid-state relay. This
isolates the PLC output interface circuit from inductive loads such as AC contactor or solenoid valve, which can avoid coil switching. The large current generated instantaneously
affects the PLC. According to the needs of input and output points and control requirements of the robot glazing peripheral equipment control system, this system uses Mitsubishi FX2N-
48MR-O01 PLC . In the external
    coil , tSB1 is the start button of the 1# motor, and SG1-SG6
are the travel switches on the 2#, 3#, 5#, 7#, 8#, and 9# motor stations respectively. soi and SQ2 are the upper and lower stroke switches of the cylinder of the transfer machine 37, and SQ3 and SQ4 are the soil level and
lower stroke switches of the cylinder of the transfer machine 7.
