Analog Output 0-10V - nhieulk - 31.05.2017

Hi everyone,

I have a problem with analog output of LM3.

When I set 0V for Ao, I check with V.O.M that I receive voltage is 0.3V not 0V.

So, these lights (controlled) with driver 0-10V not OFF. Can you check with your LM.

I have to use 1sw to off these lights.

I hope can you check these Ao of LM.

Thank you so much

There was no AO on LM3. if you mean lm3 Reactor, unfortunatly 0.3V is minimum voltage for that device/

RE: Analog Output 0-10V - admin - 01.06.2017

Yes, there's an issue with some devices with 0-10V input where it does not turn off.
LM5 reactors have different analog output schematics and this issue is fixed.

Hi,
I have the same problem with 0.3V as minimum voltage on A0 for my LM3 Reactor V.1, is there any fix for this or is the only solution to buy en new device?

RE: Analog Output 0-10V - admin - 24.11.2023

No fix for old reactor. Newer models have an improved 0-10V output which should provide 0V minimum. What kind of load do you want to control?

Hi again,
it will be used as 0-10v input to a  3RS7000-1AE00 isolation amplifier, see attached datasheet.

RE: Analog Output 0-10V - admin - 24.11.2023

It should work but hard to tell exactly without knowing the internals of this isolator.

Hi,
It does not work since I need the output from the amplifier to be 0-10v but since the output from my LM3 is 0.3-10V is also the output from the amplifier 0.3-10V.

RE: Analog Output 0-10V - admin - 24.11.2023

I'm referring to the new reactor mode. It should go to 0V due to having an improved analog output circuit.

OK, do you have any Black Friday deals on a new Reactor?
