Ao 0-24v

Hello,

Anyone have any ideas about PLCs that have 0-24V(or at least 0-20V) Analog outputs?

Use a 1k resistor over a 0-20mA output?

what do you want to use it for?
What Amperage?
Is the Analog changing regularly ie has a hertz waveform on it?
Control a 24VDC motor?

Depending on what you want to control you may want to consider a MOP ( motor operated Pot) See link

I will use it with a Sauer Danfoss PVG32 hydraulic proportional valve.

Hi Karsten

The supply is rated til 11-30 V
The signal is:
Neutral = 0.5*supply in V
A port 100 % = 0.25*supply V
B port 100 % = 0.75*supply V

Look on page 34 to see the movements of the valve.
Supply on 12V and the analog control on 0-10V
Remenber the signal current is 0.75A

JERA i know bur I have 24V suppl so i need 6 to 18 volts.

the solution with using a mA output is good possible on your wago units.
i can not see if you are using the electronic version or the coils direct.
if you use direct coils (PVHC) you can use PWM outputs. they should have 1 Amp output. 750-636 it is a DC motor output.with a simple trick you can use this for both directions just add two diodes to the coils.
If you do have the electronics (PVEO or PVEM) of the valves the current is under 1 mA. this can be done with a pwm output with low current like the 750-511. this has 24 Volt max.
