Depends on the load and how you wire it.

For smaller sites I've been known to use a small 24VDC fan for ventilation 
which consumes less than 1A, so I switch it directly with the relay.

If you get closer to the relay rating you should use an off board relay,  and 
then you use the on board relay to control the power for the coil of the off 
board relay.   The on board relay just carries enough current to power the coil 
which isn't that much except for very large relays.

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.

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?

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.

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?

Re: [AFMUG] Sitemonitor Question with Relay

[Christopher Tyler]

If you are using an external relay the load shouldn't matter to the SiteMonitor 
at all. The load would only matter for the extrenal relay itself. The 
SiteMonitor doesn't supply power accross the relay output so you would have to 
supply the external relays coil voltage across the site monitor contacts. You 
would only have to ensure that your coil volts and amps don't exceed the Site 
Monitor rating. And that should work just fine.

Re: [AFMUG] Sitemonitor Question with Relay

[Adam Moffett]

Get a DIN mount DPDT, wire it so your load is on the normally closed 
contacts.  Run the control circuit on the DPDT through the normally open 
contact on the Site Monitor.


I'd bet a Google search can give you diagrams.

Re: [AFMUG] Sitemonitor Question with Relay

[George Skorup]

I use the temp control module for heaters and fans. Same concept. The 
external relays are 24VDC coil. Contacts rated for 125VAC/10A. The load 
is on the normally-open side. The temp module calls for heating or 
cooling and triggers the correct device. e.g. turn on the fan if TempA>30C.


You're just using the contacts on one smaller relay to control the coil 
on another larger relay. Pretty simple.
