Prototype of an Auto Reversing Linear Actuator

Auto reversing linear actuator with hard wired logic using no programmable logic controllers (PLC) or smart motors (stepper with integrated driver/controller.
This system used a DC gear motor to power a screw drive linear actuator, 2 limit switches (1NO and 1NC), 2 DPDT relays (1 as a latch and 1 as a voltage reverser).
It will run continuously back and forth until something breaks as it is a prototype made of spare parts.

You don't need 2 DPDT relays to do this. You can either use a TDPT or add a Diode to just one DPDT relay.

Indeed, that's the beauty of circuit engineering, in that there may be a simpler that you haven't thought of yet. Sometimes when discussing projects with other engineers I'm lead down directions that hadn't occurred to me.

@@ERGMIAMI The Triple Pole Double Throw relay can get this done with minimal wiring and easier connection of the speed control. Adding a diode to a DPDT relay works great for simple forward/reverse but have to add a capacitor to relay and counting control. Best to use Four Pole Double Throw relay to separate the latching and counting circuits. So you have better control or flexibility depending if your counter needs a PNP or an NPN signal. I would share all the diagrams I have already made and screenshots of the simulations that I have in Google drive but KZbin doesn't let me post links in the comments. I'm going to use this in my chicken coop door with safety feature that goes back up if there is an obstruction, then back down but will only do it a preset number of times before it stops and holds at the obstruction. That way the door is at least closed as much as possible. Do you have a diagram of your project?

[@ERGMIAMI]

This is an old project. What's shown was a proof of concept. The final project was an electrostatic polyurethane coating booth for stents

[@ERGMIAMI]

The client didn't want to use a PLC. Software validation was a bitch for them.

Can you shear this circuit diagram

[@RichRocketMan]

Could someone please share how to literally make this in a step by step fashion? Thanks!

Thank you. Could you please share the wiring diagram?

If there was no switch on the left would it just stop after the full cycle

[@ERGMIAMI]

With no switch on the left, it would crash on the left.
