+/-10V analog output

[kikitron]

HI to all.

I have one project that I need to drive hydraulic proportional valve that has +/-10V.

So now I need PLC with analog output +/-10V and I found JZ20-11-UA24 PLC.

Will this Jazz be a good to drive my prop. valve or is there another unitronics product that can handle +/-10V output?

 

Thanke you in advance for you answers.

The Jazz, like most PLCs with analog outputs will drive 0-10V, not +/-10V. It is possible to convert a 0-10V unipolar output to a +/-10v bipolar signal with something like this:

Thanke you for the answer, but in documentation of unitronics JZ20-11-UA24 is written for analog output:

2 12-bit +/– 10V, 4-20mA

Hmm, when I go to their web page, here: https://unitronicsplc.com/jazz-series-jazz/ I find it says 0-10V, but I see in the specifications pdf it says what you show above (+/- 10V). I've never encountered a +/- 10V analog output, but that doesn't mean it doesn't exist. You may have to email Unitronics Support (support@unitronics.com) for a definitive answer.

I think it works like this:

 

4095 you get +10V, -4095 you get -10V

U90 Ladder shows the +/- 10V notation, so I would say that is definitive.

 

 

For the record, the IO-AI2-AO4 expansion module also has +/- 10V outputs (Jazz does not support expansion modules).

Thanke you for your help. Yes JZ20-11-UA24 has +/- analog output and its working 4095 +10V, -4095 -10V  

Now I have programming problem... but I have to open new topic in right place.
