Hi to All,
I having the 24V Solenoid Coil to activate the small iron rod. Iron piece is inserted in between the coil, whenever the 24V given to it, the coil will energize and activate the iron piece for the displacement. For this action it needs 650mA current. I will give the 24v Supply for 1Sec only, after that it remains off until it gets next activate signal.
Meanwhile, coil wrongly activate for a minute or longer time, the coils tends to heat and its burnt. To avoid this, i have used the PTC along with the coil. It will sense the temperature ratio from 0 to 60'C, when the temperature exceeds the limit, it will open up the circuit and prevents the damage, this is what i have studied theoretically, when i implement in practical, what i had thought in theoretical it comes, bu my current entirely reduced, i have to work in 650mA, but it came to 20mA. This is will not enough for me to displace the iron piece. I have attached the image, how i connected the PTC.
What my question is,
1. I have to get 650mA when PTC connect with Coil.
2. PTC has to open when the temperature exceeds the limit(0 to 60)
I have selected PRG18BB330MB1RB and solenoid is SDO-0520S-24A33
