Atnsinc 3PCS 30A Range Current Sensor ACS712 Module AC/DC for Arduino (30A)

Q: Does this handle square waves on the load. my application is for model railroad dcc.

The signal path of the AC712 is analog, so it will give you exactly what you put in. To read pulsed loads you would have to consider sampling frequently and averaging or possibly reducing the bandwidth of the sensing board. As of the time I write this, this sensing board has a filter capacitor located above the gap between out and ground (attached to pins 6 and 5 of the IC) I assume (but didn't verify) that the capacitor it comes with is likely the 1nF suggested by the application sheet. If sampling at near a multiple of the pulse frequency itself, or any other condition with a risk of aliasing, one could parallel another capacitor to reduce the filter's cutoff (at the expense of lengthening the response time) Note that this is not a flaw on this board, but just common risk that has to be managed when sampling periodic signals.
