Damn that's an impressive fucking relay!!!!

550V incoming right? Ive built some Canadian railroad panels that use 550V incoming.. What voltage are the lights it's controlling?

 

Don’t talk to me unless your circuits are conformally coated

 

550v! Lord. Are these commuter rails and you’re using the third rail or overhead lines for the train drive?

 

It depends. That relay is looking more like an old school track relay, which takes a couple of volts and a few hundred mA to pick up,but probably switches 12V on he contacts. They're big because theyre crazy reliable, and has 3 sets of com/no/nc contacts.


Relays used to run everything, it's all going solid state...very slowly.


550v sounds like something for transit traction motors.

 

50 patients in a day, new record. Also on tomorrow for that fresh Saturday shift.



Starting back at work strong with a 6 day week lolol

 

To be perfectly honest I don't know where or how they're tapping into that power.. I also don't even know if they're going in the train or just control stuff at the station. I just know if I see 550V 9 times outta 10 it's going to Canada lol

 

Back in the day I've seen some old skool factory panels that used 100% relay logic before PLCs became cheap enough to justify a new panel


The sound of all those relays actuating was deafening

 

Damn son thats bonkers.

 

I was going through some of my older Lionel model train stuff this past week. Low key, I kinda want to set it all back up on a PLC/HMI.

 

Did you ever get to play with the drum controllers that were the precursor to ladder logic? I've always wanted to see one of them.

I bet if you had a lot going on relays would be pretty loud, for us they're usually drowned out by the train

 

That would be cool. For extra nerd points, setup a signal system.

 

Healthcare in covid my man

 

Thats part of the plan. Block sections/signals etc. Gotta get my own house and a place to have a layout again.

 

Sometimes these rail systems are so old they generate it themselves because they predated the power grid. And so you get things like 25Hz AC

Bad news guys......my beloved truck is dead! Was hit day after Christmas. Just got the call. I will update.

 

long time no post.

you and yours doing ok?

 

Yea,buddy. Moved to Florida. Truck got killed. But every thing else is cool

 

yeah I remember you mentioning the upcoming move. Definitely a long haul. How are you liking it out there?

 

Anyone know what year forerunner swaps parts with a 04 taco?

 

It’s way laidback, everything is cheap. People can’t drive for shit tho..
