24V Inverter Circuit?

Hi Guys,

Is there a circuit that can invert a 24 volt signal? Everything i have found is so far is limited by voltage (ie inversion circuit using 555 timer can do 16V).

Hence when the signal is 24v, I need an output of 0, when it is 0 output needs to be 24v. I need less than .02 A for amperage per signal, i have 3 signals that need to be inverted.

Much appreciated.

You can do that with a single transistor and a for each data line.

Assuming your load is actually taking in 20mA (the 1.2k resistor is your 20mA load.

If it's not drawing any current snd just a jfet input, you'll need a pull-down resistor to drain any charge (add a 10k resistor to the PNP output).

As usual, a 555 would be a really poor choice.

It's extremely simple to do, but we need EXACT details of the circuit, exactly what's feeding the inverter, and what the inverter is feeding as well, plus what ever power supplies are involved.
