But, is the relay switching in the Packetflux bearing any of the load at any 
point?   I would think not, but the answers are a bit confusing, as though it 
is.

I would think most basic relays could be triggered successfully with much less 
than 2A

The relay is rated for 2A@30V, and 60W above that.

See https://www.mouser.com/datasheet/2/315/mech_eng_tx-1075670.pdf figure 1 on 
page 3 for a visual of this.

I'd recommend that you test the relay operation with an ohm meter before trying 
a circuit.  There should be conductivity between C and NC and none between C 
and NO when the value is set to zero, and opposite  that when it's set to a one.

If it doesn't work,  upgrade the firmware to the latest and try again. There 
have been a couple of relay bugs fixed in recent memory.   Also make sure that 
the relay on above and below rows  are set to a very high and low number since 
if that is enabled it will override the relay.

The typical solution with a light-duty relay is to use it to control a heavier 
relay that carries the actual load.

do what we want and maybe we just have the wrong external relay

Yes, there is a relay output on the siteMonitor II that you can trigger via 
SNMP or web interface.

Subject: [AFMUG] Sitemonitor Question with Relay

My service manager seems to be struggling with using the Sitemonitor Relay 
contact to trigger a 48 Relay that we want to use to power cycle the whole 
tower if necessary.  So, Packetflux states that the Relay control is maximum. 
30v 1amp.  So a little more than half the amps at 48v.

So, in the past (lighter loads on towers) we used this to trigger an external 
relay and "open" the ground to the main power feed going up the tower.  At 48v, 
we sometimes are around 2amp on the bigger towers, some perhaps a bit higher 
still.  (with a 48v relay).

We should be able to use the Sitemonitor to somehow accomplish it.

Can anybody comment on this?

Thanks!
