Solid
state relay module
This
module changes a 5V DC input to a 120V AC signal to turn the pump on or off,
to build pressure in the hydraulic system, and to start the fluid flowing.
These signal are sent to the distribution
panel. When the switch is set to EXTERNAL, the output of the logic
module (which is 0 or 5 volts) is the input at the CONTROL BNC. When the
switch is set to ON, a 5 volt signal is generated and when it is set to OFF,
a 0 volt signal is generated. The D1210 solid state relay will output 120V
AC when 5 volts are generated.
