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.
