Overloading a Servo Through the Trigger Pin?
Overloading a Servo Through the Trigger Pin?
(OP)
Hello all,
Sorry in advance for the "stupid" question, but i just couldn't find the answer online and i want to be 100% sure that the component will not be damaged.
I'm using the SAVOX - SW0241MG, the servo is rated for 7.4VDC.
To control the servo I'm using an (Arduino based) PLC, the servo and PLC each has its own power supply.
The output pins on the PLC generate a pulse of 24VDC.
Might the servo be damaged if i connect its trigger pin wire to the 24VDC output of the PLC?

But do read up on voltage dividers.

Yeah the specs provided by the servo manufacturer are very basic.

You can use a Zener diode and a resistor to solve the problem.
Put the Zener from ground pointing to the servo pin and the 10kΩ resistor from the servo pin to the PLC. Use a 7.2V Zener.

Instead, use a voltage divider to reduce 24v peak to 10v peak: so do the math. Short the math, use a 15k in series with a 10k resistor, and feed the servo from the junction of them
