Pool equipment control

[dgbrown]

Looking initially for some basic pool control: pool light and booster pump control.

Considering pairing up a couple of RIB's (http://www.wolfautomation.com/ProductList.aspx?ManufacturerID=1381&gclid=COP_6vvI3rYCFcuj4Aod_WAAyA) with a Card Access Relay/Extended. MEA 4 rated enclosure would be required for install out by the equipment pad. Other than that doesn't seem too complicated.

Wondering if anyone has used these Relay-in-a-box products ? Any thing I'm missing ?

Also, they have new wifi product out http://www.functionaldevices.com/building-automation/display.php?model=RIBTWXV2401B-WI that looks great but a driver would be needed.

Thanks in advance.

Not the specific ones you have linked too I believe, the only thing to keep in mind is that not all (specifically the multi voltage input ones) provide power to close the relay so some form of external power would be required.

On card access relays you can often do this using the power supply it comes with (one jumper from - to common, returns from RIBs to + terminal). Provided it can supply enough power and the correct voltage of course.

Wouldn't you be best served by Card Access units available in 110 and 220 for this? No need to write new driver. Also Axxess Industries make a nice Zigbee unit for 110V with 3 x relays and 3 x contacts with optional POE.

Aside from using the Card Access Heavy Duty Relay $$$ - the other CA extender/relay still requires the use of an external high voltage relay, which in turn switches power to the pump and lights (one relay per).

The only nice thing about this specific new product http://www.functionaldevices.com/building-automation/display.php?model=RIBTWXV2401B-WI is that it is controlled and queried via the query string of a url via an embedded webserver in the relay meaning it can be operated without control4 or zigbee via wifi and any standard browser. A driver would be necessary for Control4 integration.

This relay can be controlled in a similar manner as the Irrigation Caddy sprinkler controller - surprised no one has created a driver for that yet either. In a pinch for one way control I suppose the jpg driver could be used with a custom button.

BTW, Axxess does not have a high voltage relay that I'm aware, it's LV only and would require an external high voltage relay too.

Which is why he mentioned the RIBs.

For 220V loads up to 20 amps, I use these Aube units frequently http://www.aubetech.com/products/produitsDetails.php?noLangue=2&noProduit=42 . Still need to be paired with a regular Card Access or Axxess Industries unit.

^ I think this may actually work better than the RIB for the booster pump (which is an inductive load rated at 3/4 HP). Though the filter pump is is 1 3/4 HP and I believe exceeds the inductive load rating for the relay.

Thinking this might be a better fit for an inductive load since it's solid state though: http://www.aubetech.com/products/produitsDetails.php?noProduit=44&noLangue=2

I like the idea of separating the LV control (eg. using a CA piece) in that I can tap a pipe for temp as well ... and if I ever wanted to change things up down the road the wireless control can be swapped easily without altering the HV wiring.

Edited to add:

Ok, now I'm confused by the specs. The 840 is mechanical and spec's include an inductive load. There is also reference to use the 850 series for inductive loads, the spec sheet of which does not include a spec for inductive loads.
