Great that the GX IO-Extender 150 contains bi-stable relays, I love the energy savings of bistable.
In my home, that needs to be made smart, the loads I want to switch on and off are always more then 125VA.
Dear Victron, please supply an GX IO-Extender with latching relays that can actually switch a load. For example use Tyco RT2 series: up to 2000VA, 8A (UL: 10A) and up to 400VAC and [strike]110[/strike] 250VDC.
More product feedback: skip the solid state relay and other i/o, I’d rather have more relays for load (> 90W) switching.
PS The Victron datasheet “maximum switching power” diagram looks similar to that of the Hongfa HFD2 series.
Wireless is something I don’t like, so no Shelly here.
The Hongfa HFD2 outline dimensions measure 20.2 × 10.2 × 10.6 mm¹
The Tyco RT2 outline dimensions are 29.0 × 12.7 × 15.7 mm¹
Alternatively the Hongfa HF115F-L is also 15.7 mm¹ in height.
Skipping the 8 i/o ports will bring enough space. The height difference is only 5.1 millimeters: GX IO-extender 150 datasheet states 23 mm in height. A guesstimate for 1 mm wall thickness, 3 mm ground clearance, and 2 mm for the PCB leaves only 16 mm for components. That’s a tight fit.
The SSR may stay. The first time I read the datasheet, I missed the part that the SSR is intended for switching batteries. That is my use case too: disconnect a Studer AJ-400 in standby from the battery. (In some versions of the datasheet, the TE RT2 has a 250VDC 0.2A EN60947-5-1 rating for only 6K cycles)
It’s difficult to find ready-to-use double [strike]throw[/strike] pole bistable switching hardware that is able to switch 300-400W loads. I can’t even find any populated PCB within spec for an rPi.
Hi. I agree with @cj0 in regards of the bistable relays. More relays and higher current ratio is needed. And the IOs are also needed - maybe in a 5-24V Version.
My focus is mobile usage. The function of switching devices from the Venus GUI was the missing part to be the central element in RVs or boats. The current setup needs coupling relays for the IOs - and they are not bistable.
To make a whish: 4-8 bistable relays 30V/10A, 4-8 open collector outputs, 4-8 digital inputs 5-24V, 2-4 analog Inputs 4-20mA/0-10V (tank sensor) - call it the RV or boat module and a lot of people are lucky (I guess)
I’m happy to have the GX 150 but was a little surprised at the limited current switching ability of the relays. On the plus side, the GX 150 is easily integrated into VenusOS. But, to switch any real loads you will need the relays to control a larger relay to control the load. I like having the digital I/O as well. And, the GX 150 works with 12V, 24V, and 48V systems.
If you’re ok being limited to 12V or 24V, check out the SmartSwitch from Energy Solutions. It, too, has direct support in VenusOS.
@mpvader Thank you for the continued evolution of the GX devices and providing more means of control and automation. Now, if we could just get grid codes for the USA
Yes, the smart switch ist quite interesting - and than I found this: https://safiery.com/ THAT is really cool. Just looking for a distributor in EU …
Victron os is on the direct path to becoming an ingenious central system for RVs and boats
