Wire an SSR to a DB25-1205 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.

STEP 03

Wire DC side of SSR

What is an SSR?
An SSR is basically a switch that will turn off and on a single wire but instead of having to push or flip a physical switch, you simply supply a currant to the signal side of the SSR to activate it. The advantage of this is being able to control the SSR with an electronic device via a program to turn equipment off and on (like your router). So the basic concept is the SSR doesn’t supply a current itself, rather it is a component used in line with the incoming current to a device and is used to switch it off and on remotely.

A Quick Overview
The following diagram will give you a quick overview of the SSRs terminals, mountpoints and data plate. 

  1. AC Live In
  2. AC Live Out
  3. DC-     (Control Signal)
  4. DC +   (Control Signal)
  5. M4 Mounting Points
  6. Activity Indicator (LED)
  7. Max Amperage of SSR
  8. Control Currant and Switching Current
  9. Range of current that can be switched on/off (from mains power)
  10. Range of input signal current (from Breakout board)

With a Philips head screw driver loosen of terminals 3 and 4 on the SSR.

Insert the spade connector from the DC+ wire into Terminal 3 (marked by “+ 3”) on the SSR. Then insert the spade connector from the DC- wire into Terminal 4 (marked by “4 -“) on the SSR.

Retighten terminals 3 and 4 on the SSR.
