Hiya!
Ok so I have a 24VDC brake that is messing up and its because when the voltage to it goes to 24vdc or more, it deactivates (releases brake), but the drive going to it needs to shut off (go to 0Vdc) to apply the brake.
Normally 24vdc = brake release
Normally 0vdc = Brake applied
However.... I am getting 16vdc when I need it to goto 0vdc to apply the brake.
The voltage comes off a large servo amplifier board. Instead of buying a new board (tons of money), im tying to design a simple DC relay circuit to CLOSE when 24vdc or more is applied, yet OPEN the moment 20VDC or below is seen, with NO DELAY.
Can anyone help or point me to a design? I have tried many setups with simple relays, but the residual voltage is keeping the relay closed, until about 5+ seconds go by and then closes becauses of losses.
Thank you in advance! Yall are awesome!
