Hi, I need advise to convert these relays contacts to transistors. I cannot find anywhere this designs in internet. So I come here to ask hekps from masters of electronics.
Is there any IC to replace this method insteads of using too many transistors. If able to use IC, this will reduce complications and pcb space.
What will be the differences if L is 5V vs 12V?
If one relay is switched on, the other relay must not switch on.
Is there possible to a third relay? The rule also applies, 1 relay switch on, the other 2 must not switch on.
* MC-1 NO and MC-1NC contacts are belong to MC-1 Relay.
* MC-2 NO and MC-2NC contacts are belong to MC-2 Relay.
* Use transistors or IC to replace all of these contacts of MC-1 NO, MC-1 NC, MC-2 NO and MC-2 NC.
* Voltage on L is 5V or 12V.
* Please ignore the contacts for motor side. I took this picture from the web. It is similar but not for motor forward reverse.
