Using the Apex with a UPS Battery Backup

I'm going to see what I can come up with. I'm no electronics guru, but I can follow a schematic. Since I was in the process of a DIY breakout box, I think I'll add the power failure relay. My basic assumptions are to use any mechanical relay that uses a 120vac coil trigger. Since the switch contacts will only be used to pass continuity to the apex, I assume nothing else is needed. Does anyone know if there is any transient voltage passed to the contacts from the coil? If there is, I would think it would be bad for the apex. Can anyone chime in on this topic?

I have this exact setup you are referring to and it works fine.

I have two different 4 plug 15A circuits for my tank and have 1 EB8 and 1 DC8 plugged into each circuit. In order to monitor the power on the DC8 connected circuit I have a 120v relay plugged into one of the wall plugs. The switch side goes into my breakout box. If power is lost, the switch closes and sets off an alarm.

I created a virtual outlet names Power_DC8 just to clean it up.
 
tamu - do you have a source or link for that 120v relay?

I am using a light duty SPST 120v relay; one like this http://parts.digikey.com/1/parts/752325-relay-pwr-open-spst-no-dm-120vac-prd-3ay0-120.html

Mine is a bit smaller than this as this on is heavy duty. I'll look for a PN and manufacture when I get home. I will add mine right to my DIY breakout box I have not wired it yet, only to test theroy.

I actually stopped with the build because I wanted to find a relay that I could use on a PCB/bread board. I also plan to add LEDs to the box so I can tell where I have opens and closed for the switches. Maybe I will just build it seperate for those here that want to build as well.


The drawing is pretty simple and the relays generally have the schematic printed right on them.

When I get it wired up, I will post a build thread.

No, it was a long time ago that I put it together and it is tucked away and very hard to get to at the moment.

I used a socket connector and a plug-in relay. The sockets are nice, because they have screw down terminals for your wiring.
 
I bought a 12v ac adapter from Neptune and I have 2 eb8's. I bought 2 very small ups battery backups. One for my cable modem and router and the other for my wireless bridge.
From what I understand I should plug the ac adapter into the wall and one of my eb8's into the UPS. Does it matter which eb8 I plug into the ups? The ups are very small so I don't plan on using them to run any pumps or powerheads.
Also which code do I use to get power outage emails?

Set Off
If power eb8_3 off 001 then ON
If power eb8_4 off 001 then ON
If power apex off 001 then ON

I have to turn enable power monitor on as well
 
What exactly do you plan to plug into the UPS-backed EB8? If you are not planning to use the UPS to maintain water circulation - which IMO is the most important equipment to keep powered up in event of a power outage - then I see little point in providing backup power to the UPS. And how small is "very small"? Tell us the listed rating of the UPS in VA.

It doesn't matter which EB8 you connect into the UPS - what matters is what's plugged into that EB8.
 
Can the 12 volt supply and Socket Expansion 120V from Neptune be plugged into the battery backup and remain on in case of power outage? and still have the eb8 show no power?
 
guys just so ya know idk if there is another thread or something but you can now detect power outages through the 12v adapter in the controller... so you plug the power strip into the ups, and the controller gets the 12v adapter plugged into a non ups jack... and you can program based on outages..... straight from the neptune manual... but you have to enable power jack detection through the display you cant enable it through web interface.
 
Many UPS have a DB9 connector, or possibly an RJ serial connector that can produce a NO or NC (normally open or normally closed) contact state for integrating with network monitoring devices. Read the UPS manual to find if it does and what pin out is required to interconnect it to your I/O inputs.
