Read from encoder, read from torque-measuring disc, write to hydraulic controller (HPU) and write to solenoid.

[Read from encoder, read from torque-meas]

We are trying to make a complete program to steer a test bench.
We shall simulate a torque using a disc brake that is steered by hydraulic
vents.
The encoder will give the position, and turns.
There will be no more than 20turns.
To measure the torque we use a torque-measuring ring, and after 20turns a
solenoid will stop the disc completely.
The card that I choose AT-232/4 may not be the best to use?
But 4 channels would be enough.
2 to read encoder and torque measuring disc.
2 to steer the hydraulics for the brake and solenoid.

The AT-232/4 card is a Serial card. Does your encoder, torque disc, etc., all use serial commands/protocol? What's the acquisition speed you are aiming for?

The above, among other things, determine whether or not the AT-232/4 is the right card for your application.

Khalid 🙂

If you have some of serial feedback you may have the correct card. However, if you are wanting to read from quadrature encoders that output a normal TTL signal, you have at least two options for reading them, our 7344 & 7334 Motion boards, or you can configure one of our DAQ boards to interpret the encoder pulses. Our Motion Controllers have the ability to control motors (7334-Steppers, 7344-Stepper & Servo) and gather positional feedback via a quadrature encoder. Both are four axis boards.
I hope this helps!
