hi,
my company uses an Ac coil to control an auto drain system, the AC coil works on 230VAC/50hz ,we use a 4541 timer and L4004V3 TRIAC to switch coil
ON and OFF, my problem is some times the plunger get stuck and damages the coil and in turn damaging TRIAC and circuit,
I need a solution to prevent this problem, will a fuse on Coil line solve this or is there any circuit solution to indicate Coil is damaged ?
