Although it's hard to determine if you can only power one Line sensor per Solenoid output. (We'd like to power all three from one output)

Since you can only power ONE soelenoid breakout with 24V, you may find yourself running out of solenoid outputs...

eg: 3 double acting solenoids will consume 6 outputs, leaving only two to power the three line sensors.

Question: How does the load of one Line Sensor compare with the load of one Solenoid?
