[4-20 mA I2C] Module response time

This is my first time on this forum, and I just need a quick answer about the response time of the I2C 4-20mA DAC Module (SKU : DFR0972).
We need this product to be involved into a test bench for a train to simulate the 4-20 mA output of a speed sensor on the bogie.
I cannot find any info about this online, since I don't even know the I2C chip's name.
Thanks by advance,
Hugo
If you're simulating sensor outputs for monitoring bogie speed dynamics, you can count on the module to respond in well under 10 ms for each command, especially since the hardware startup is so fast.
For more precise measurements, you could add a timestamp logging of when the I2C command is sent vs. when the ammeter reading changes to benchmark the full cycle in your test setup.
