DSP connection

[julienb74]

Hello,
I’m building a 50W Co2 laser
I’m going to buy the DSP controller, water pumps…
I looked the DSP connection, I don’t understand, I see the water protection connection (it’s a sensor?)
But where do you connect the pumps, the air compressor, the exhaust fan ?
Thank you for your help

Water protection is a sensor and the rest do not get connected to the DSP.

Hello,

thank you for your answer,
I seen the exit IO on the main board, I can connect my relay for the air blower, exhaust fan, can I connect here the water pumps ?
When this exit IO is activate ? (at program startup or only when the laser shoots or another time?)

Thank you for your help
