At only 100Hz you've got options to put a small cap. filter on the AC or DC side, across pins 2 & 3 on the AC side. --- End quote --- AC side - this appeared to me to be to filter noise on the AC input, so I did not try it since the noise was on the rail. DC side (of bridge) - same reasoning as AC. DC output - adding capacitance here is for filtering the output pulses so that a change in output only occurs when the AC comes on or off - for app's that desire this function. This would slow the signal down of my pulses and wreck the shape of it, and it may not solve the problem that I had, was my interpretation. |
