Simulator for automotive and valve

[vlelectroniclab]

Good evening everyone,

As described, I'm building a simulator for the automotive sector. Basically, I need to:
OUTPUTS:
2) PWM valve with current control (PWM, dither, current open/close loop 0-2.5A)
2) There are eight control modes:
-10V... +10V, -2V... +2V, 0V... +10V, -10mA... +10mA, -2mA... +2mA, 0mA... +10mA,
0/4mA... 20mA, -20mA... +20mA.
1) Analog output current 0-100mA
INPUTS:
2) Integrated potentiometers
4) 0-10V input
4) 0-20mA input
4) Frequency input for PNP/PN sensor (VR sensor optional)

use teensy4 with nextion 5inch display
This is still a draft.
How can I generate all these signals?
Any hardware advice?
Thanks

Pwm frequency 20hz to 2khz
bandpass filter is problem!!

Hello,

My collegues from electrics use these converters:
Lutze 817006 programmable U/I to U/I converter.
WAGO 857-500 frequency to U/I converter
WAGO 857-423

And some other converters from the same familly.

First up...

What are you trying to simulate....?

Then, I am guessing, you want to control something from the Teensy and what you want to control cant be controlled directly from the Teensy and will need some sort of driver module.....and for the Teensy inputs.

Unless we know what you are trying to control and how, we really cant give you the best answer
