Solid State Relays take something like 30 mA. From: Paul McCall Sent: Tuesday, April 10, 2018 11:45 AM To: af@afmug.com Subject: Re: [AFMUG] Sitemonitor Question with Relay
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 From: Af <af-boun...@afmug.com> On Behalf Of Forrest Christian (List Account) Sent: Tuesday, April 10, 2018 1:44 PM To: af <af@afmug.com> Subject: Re: [AFMUG] Sitemonitor Question with Relay 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.

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!
