Wire an SSR to a X214650 BOB 3

Wire an SSR to a X214650 BOB

DO NOT HAVE YOUR ELECTRONICS, ROUTER OR EXTENSION CORD PLUGGED IN WHILE YOU WORKON THEM!
Check that you can see the pronged plugs of the router and extension cord are not plugged in.
Best practice –¬†hold the plugs in your hand and visually trace the cords back to the router and other end of the extension cord. This will confirm they are not plugged in.

Wire SSR to X214650

A Quick Overview
The following diagram will give you a quick overview of the X214650 breakout board. 

  1. DB25 LPT Port (connects to PC or Smooth Stepper)
  2. DC 5V+ input terminal
  3. DC 5V- input terminal
  4. Power LED
  5. Unassigned (5V+) Output terminals for pins
    1, 2, 3, 4, 5, 6, 7, 8, 9, 14, 16 and 17
  6. DC- terminal (5V-) for Output terminals, shared by pins 1, 2, 3, 4, 5, 6, 7, 8, 9, 14, 16 and 17
  7. DC- terminal (5V-) for Input terminals, shared by pins 10, 11, 12, 13 and 15
  8. Unassigned (5V+) Input terminals for pins 10, 11, 12, 13 and 15S

As the output pins are unassigned you can choose any unused pin to control the SSR. In this example we are going to use Pin 9 as it’s a fairly common pin assignment used to turn a spindle off and on. If Pin 9 is in use you can choose any other free pins 1, 2, 3, 4, 5, 6, 7, 8, 9, 14, 16 or 17. You cannot use any of the input pins as the optocoupler is the opposite was around to an output pin.

Once you’ve decided on an output pin run the DC+ wire from the SSR to the terminal and trim off any extra wire. Remember to leave a little extra as you don’t want the wire to taught.

Then strip the wire back around 4-6mm. Give the wire a twist and make sure there are no loose strands sticking out.

With a small flat head screwdriver loosen off terminal 9, insert the DC 5v+ wire and then retighten. The DC positive wire connected to terminal 9 MUST got to Terminal 3 on the SSR.

Run the DC- wire from the SSR to the GND terminal and trim off any extra wire. Remember to leave a little extra as you don’t want the wire to taught.

Then strip the wire back around 4-6mm. Give the wire a twist and make sure there are no loose strands sticking out.

With a small flat head screwdriver loosen off the “GND” terminal , insert the DC 5v- wire and then retighten. The DC negative wire connected to the GND terminal MUST got to Terminal 4 on the SSR.

The 12 output terminals on the BOB all share a single DC- terminal (ladled GND), this means that all the DC- wires from all your connected devices must all come back to that single connector. You can get creative and link the DC- wires from device to device or splice them into each other as you go, but I’d like to recommend using a Bus Bar Connector for the “GND” terminal as pictured below. They are reasonably inexpensive and make the installation process simpler.
