Similarly, the other two relay switches controled the flow of electricity from the power supply to the motors and are activated by the PLC. The motors’ feedback system went through the voltage regulators to lower the voltage from 0-24VDC to under 0-10VDC and links to the PLC’s analog input connection.
The motors’ feedback system went through the voltage regulators to lower the voltage from 0-24VDC to under 0-10VDC and links to the PLC’s analog input connection. The CPU was fed 240VAC from either a power supply or an outlet, and it was converted to 24VDC. This supplied power to the switch module and the HMI screen.
