    Do you have any more info on the relay board, or more pics?

    You should just need to wire one of the outputs from your RnR board, along with 5V and COM.

    putting together data from various web sites this is as close as I can get to the circuit of the dual relay board

    Need help with relay on usb card bsmce04-pp bob-relay-board-circuit-jpg

    with the jumper JD connecting the two VCC terminals

    Need help with relay on usb card bsmce04-pp bob-relay-board-jpg


    on the 4 pin connector
    you will need to connect a 5V supply to the VCC & GND terminals

    the GND needs to be connected to the USB controller GND and output to IN1 (or IN2) on the relay board


    John

    PS

    do you have a link to a manual for the 4 Axis Interface Driver Motion Controller ??

    assuming the part of the board with the micro controller is powered by the USB port

    it's not clear from the photo how the opto-isolated outputs and inputs are powered or
    what the IC next to the four outputs is
    can you read the part number ?

    found a photo on the net that shows the 16 pin IC connected to the outputs is a ULN2003

    Need help with relay on usb card bsmce04-pp bob-4-axis-interface-driver-motion-controller-jpg


    pdf data sheet
    ULN2001 to ULN2004.pdf


    terminal DCM (next to input IN1 ) looks like the positive supply for the input & output circuits
    going by the value of the resistors on the pcb it should be OK with +24V

    the negative supply being the common connection for inputs IN1 to IN4 and outputs out1 to out4

    update

    after finding more a detailed view of the board
    this is the input and output connections on the board

    Need help with relay on usb card bsmce04-pp bob-4-axis-interface-driver-motion-controller-update


    with this information the answer to the original question

    Need help with relay on usb card bsmce04-pp bob-relay-board-connection-motion-controller-jpg

    the e-stop or limit switches are connected between the common DCM terminal and one of the 4 inputs (IN1 to IN4)


    the relay board's GND needs to be connected to the motion controller DCM

    one of the motion controller open collector outputs (OUT 1 to OUT 4) needs to connect to
    one of the relay boards inputs (IN 1 or IN 2)

    hi all

    some body know, how I can connect the limit switch in this board bsmce04-pp, and also I want to connect Diode Laser, which is the correct connection the lase is PWM or TTL

    thanks, AR

    is your laser diode like this ?
    Need help with relay on usb card bsmce04-pp bob-4-wire-laser-module-ttl-enable-input

    if it is connect the enable to the + supply and
    TTL input to the bsmce04-pp PWM output

    I don't have a detailed manual to know if you can use one of the 4 outputs (output 1 to ouitput 4)

    john
    Could the +5v from the usb section of the controller be used for the Vcc on the relay? Or is that a bad idea?

    hi John Good afternoon

    My laser is different it is for TTL and PWM, but I want to know how I need connect it, want to control the intensity directly from my control.

    thanks, regards.
