24V Inverter Circuit?

[Iawia]

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).
