hello,im looking for a tacho loss relay to substitute a broken one in a machine.i cant find the original make,and looking around there doesnt seem to be anything suitable.
the tacho is 0.06v/rev.the max revs of the motor are 2000rpm.
at drive enable and minimum speed there are approx.600mv on the tacho line,this unit,when it worked gave an input to a plc which enabled speed up etc.i know there are voltage level detectors ,0 a 10v with
histerisis etc,but at 2000rpm i have 120v.
does anybody know of a unit that will give me an ok output at 600mv,and at the same time support 120v on the input side.regards,tony.
