Do you have basic electrical/electronic skills? Very important to be successful and to be able to work your way through the conversion. Use the Generic VFD wiring as a guide. You will connect 24VDC from Acorn logic power supply to the COM terminal of that relay board. You have 8 relays. The older r...
