I don't know that's the same "180" unit as the similarly nammed TMCC/Leg. units meant for command. The whole line doesn't use the same systems. Im not saying it will or won't work; I take the err on the side of caution approach. ...some folks dive in deep without looking. I assumed you run conventionally but use modern equipment and would like to access at least some extra features.
You can make a diode whistle/bell controller with a higher offset to trigger PW whistles. Stubborn whistle relays need more offset, the modern stuff seems more interested in seeing the wave shape of the diodes more so than the offset, a "change" has to happen faster. Add another diode for the offset chain to plans found in threads here for more offset.
I'm thinking a polyfuse might be interesting to play with to add a lower offset holding voltage.(takes way more voltage to pull than hold a relay=way less heat if you can lower it in an instant) (this is the "half way handle" effect on getting postwar transformers to force some whistles into action, it boosts the offset for a second when thrown normally. Halfway holds the big offset.)
A homespun whistle/bell can incorporate a voltage boost(or drop) to better mimick the PW transformer 5v boost, or your custom boost liking.
This knocks a near equal amount of voltage boost, off the top voltage (v=speed of motor). I doubt you spend a lot of time with the throttles near pegged, so no loss for most trains anyhow. It would take a few more throttle volts before things move ("saved" until boost is called for). It's actually more like an voltage governer you release, and make an offset with. Youd need one for each throttle if you want it everywhere.
I run mostly command with DCS And Legacy. With the PPD(Pure Power Dual), when I blow the whistle or sound the bell on a conventional engine (Lionel or MTH) the train does slow down.
