This a relay CNC I/O Module designed for use with the 6 Pack Universal CNC Controller. It is for use with Spindles that require a 0-10V signal to set the RPM. It also has the 2 signals that are typically used to signal forward and reverse directions.

Features

• 0-10VDC signal. You will need to adjust the pot to get the voltage you want. This allow you to set it for 0-10V or 0-5V. The default value of the pot is usually around 0-8V.
• (2) Opto isolated signals for forward and reverse. The signal pin is connected to the COM pin when active. 
• LEDs for 0-10V and each direction signal.

Buying assembled from JLCPCB

They will only assemble one side. You should specifiy the top side. You must purchase and solder the 12 pin header on the bottom. It is a standard 0.100" (2.54mm) pitch header. You can buy snap off style many places or the exact part here. LCSC part number C225487

You also need to buy the mating terminal block (Cixi Kefa Elec KF2EDGK-3.5-5P) from LCSC

Both those parts are on the BOM of the schematic.

PCB Specs

You can use all of the defaults. I typically change the solder mask to black for 6 Pack modules.
