How Do the SSR Output Modules Work?Hardware: Signal Conditioning Other>>SSR Series
Problem: I am trying to assemble a system involving power supplies, SSR backplanes, solenoids, strain gage transducers, thermocouples, and a counter. I am somewhat concerned about the voltages involved.
I have a 5 V power supply for the SSR backplane. Solution: There are two terminals on each SSR (Solid State Relay) module and each module has one relay. When the module receives a TTL Low signal from the computer, the relay connects the two terminals on the SSR. When it receives a TTL High signal, the relay disconnects the two terminals. For example, if you connect a 24 VDC power supply and your counter to the SSR output module, then every time the SSR ouput module receives a TTL Low, it will relay the 24 VDC power supply to your counter.
