Yes, the M-84 should work! Thanks for watching, sorry that some of these academic instructional videos are not very exciting to watch. For older signals with a solenoid (built in electro-magnet) it is better to use the momentary pulse provided by a M-83.
Hi ajckids, question does the M83 decoder have the same insulation ? Is it possible to connect a manual turnout control in parallel with the M83 outputs?
No, this is one of the big differences between the M83 and the M84. The M83 uses the digital power from its digital signal to feed all the ports. You can use a 60822 universal power supply with suitable power pack (here in the USA we use 66367). When you connect the 60822 to the M83, it uses the power from the attached power pack to feed the ports. ajckids.com/products/marklin-60822 ajckids.com/products/marklin-66367
