I'll email the manufacturer and tell you guys what's the set up with this one. If the actuator does have an in built surge flyback mechanism due to limit switches with diodes built in would that mean that I don't need to protect the circuit from this anymore?
So in my thread subject and initial post I did mention that I could change my component specs to suit myself. If I instead used a 24vdc actuator which can draw 8a (as opposed to 12vdc 16a max load) would this circuit be any safer? Would short circuit arcs still be a potential problem?
I have no...
I really don't know.. I contacted the manufacturer whose told me the motor has 2 leads. The actuator specifies that it has limit switches built in. I agree on the potential simplicity of this entire thing. Thanks for pointing it out. Just want to understand how it could all tie in.. it's more...
So I've read up on back emf a bit. It seems like you'd add diodes across your at risk components like the relays in this case. I feel like I could be missing something though.. is it that simple?
Tom and pbuk. In the other thread someone had mentioned transorbs and having in built transorbs to your relay as a means to handle the bank emf. I'll look into this and post. You guys can tell me if I have the right idea or not
These spdt relays are quite cheap and readily available. It is more economical to build this circuit than to buy a motor controller. The H bridge system with 2 spdts seems very simple to build. Thank you so much. This was a huge help
I made this circuit as a means to prevent shorting in the event that both buttons (up down) are pressed at the same time. Please take a look and comment. Not sure if it's right
I am fast coming to the conclusion that a premade forward reverse motor controller is much more economical then building the circuit myself. I also see heatsinks on allot of the products
