Sure hope I was not the cause of making you hang over in Ephrata for the night?
If ya wanna just ride here on Tuesday I can offer a clean, comfy bed and TV in a bedroom cluttered with storage items around the walls.

nah!! I will just make it a short 200miles ride to ephrata taking the sights there !!!!!! and be all rested for wesdnesday

Sorry - late to the party, was overseas on family emergency



PDM60 info:

Physical size is
Main body (excl tabs) 78 x 53 x 23
The width including the mounting tabs is 98mm; the mounting holes are 88mm between centres.

Features:
Each circuit is programmable for current and can constant on*, ignition triggered or ground triggered.
Start-up delays (will not come on until selected time after trigger) or delay-off times can also be programmed

The triggers can also be combined so that you can have a circuit that requires BOTH triggers to operate.
e.g. say you wanted to power an air horn; use the OEM switch as the negative trigger and the horn would operate only when ignition is on and switch is pressed.

The limitation of the negative trigger is that there is only one, so realistically can only independently control one channel

*A couple of limitations of the "constant" power:
1. It's really not constant (necessarily) - if you have a delay-on programmed, it will actually turn the constant off during the delay period
(start-up delays apply to all circuits - so you either pick zero time or have delay for all circuits - unfortunately also seems to apply to the 'constant'-on. This seems to be a bug - I have reported to Rowe and awaiting feedback.) In reality this is not typically a concern unless it was powering something that really HAD to be constant to maintain a memory for example (will not matter for most devices and fact remains it WILL be on with ignition off, which is why you would use that setting in the first place)
2. If constant-on circuit is programmed, the module will draw about 60mA standing drain with ignition off. That may be OK for a big battery (like on the R3) but would be concerned if parked for extended periods (longer than a week) without being ridden or on tender

But it's a really nice device - solid-state MOSFET switches with excellent programmability and fuse-less short-circuit protection with diagnostic LEDs

The other questions:

Does not dissipate heat, so no heatsinking required even at the spec'd 60A (which is unlikely anyone will be drawing).

Ground system - that really is independent of the positive power distribution and you can use whatever type of ground BUS you choose - I actually think the supplied ground pigtail is a decent solution without adding complexity and associated cost. The module only sinks minimal 'ground' current through the module itself, <100mA for the control circuit. The Ground to the device has nothing to do with grounds for the accessory circuits. I do not recommend grounding any device to the frame - it is not an electrical circuit component, no OEM circuits use the frame - this is not a car. So use a ground BUS connected directly to the battery negative.

For the money vs the Fuzeblock or PC8 for example or it is WAAYYYY more sophisticated in its capabilities but of course costs more, and similar to the Motogadget which is significantly over-priced for what it is IMO.

Disclaimer: I am a supplier for these devices so you may consider my opinion coloured accordingly; however I have tried to give an honest assessment of its pros & cons.

Thanks. I have two on their way from the UK disti'.

But those precise dimensions are really good news.
As is Zero Heat Dissipation ;)

The negative trigger limitation is why I have two coming. Oh well - it's only money - Just don't tell my missus.

I have two Ground-Bus systems in mental mastication. May well be a combination of both.
Now I have the dimensions I can away and machine tomorrow. I hate machining in the afternoon/evening.

I sadly know all too well about Overseas Family Emergencies - hope it was not too serious.
Accept my commiserations if 'twas!

I designed and supplied a 2xPDM60 (with Key-Less*) total Fuse-box replacement system for a Sprint.
Ended up eliminating Fuse Panel and 3 relays - the ground switches were for the air-horn and the high beam in his case.
I actually also designed an additional single-channel solid-state switch to use with that also
(if you need any additional independently switched channels let me know - can supply or tell you how to DIY)
Extravagant yes, but it's a really neat system.

* Since it's "only money" how about adding a Hands-free Key-Less to the equation? :D
The Key-less drives the PDM60 very nicely! ;)
 
My Mk1 system used similar with a tag - I like the hands-free feature personally, no need to do anything except have it in your pocket.
 
Mine is 3-5m - and hands-free.
And the remote battery life is >1 year
(it sleeps when out of range and when ignition is on so limited drain)

I am on a one-man crusade to kill batteries.
The little bastards always fail at midnight - 300 miles from anywhere, in driving sleet.
And here's the thing - they're designed to fail eventually.
