hey guys,
Im using a active low PLC with a supply of 24V, and need to run a 12VDC stepping actuator.
The board can supply 400mA, and i only need 129mA, so thats fine, but needs only 12VDC.
As I understand, the +ve supply is connected to the actuator, negative back to the output pin. Once turning "on" it pulls the output pin to 0V, hence curent flows in.
Thinking of the best way to get the 12V, do you think just a simple series resistor on the +ve supply terminal.
Drop 12V, with a draw of 128mA, so about a 100R?
Ideas?
