I'm presently doing some research into a SNMP-enabled device to monitor a set of aux contacts on our transfer switch in order to be able to monitor it's status (on generator or on commercial) from our monitoring platform. I've seen a few interesting devices out there that can accomplish this, however I thought I'd query the list to see if anyone has thoughts about a particular unit they've worked with. Thanks in advance, Tom

I went a different way with my electrical gear and used modbus. For me, the benefits are multiple devices on the 485 bus, monitoring lots of parameters and I can execute remote commands. I paid something like $300 for the xfer switch modbus card, which was cheaper than any SNMP contact closure device I could find at the time. I talk to it using Perl Modbus::Client with my monitoring server as the modbus master. It ended up being less of a hassle and much more flexible in the long run. You may or may not have your mind set on dry contact monitoring, but it's something to think about. ~Seth
I have used the APC Environmental Manager (EMU) to do this. In our case we ran a 4-pair line from the generator to the EMU. One pair was connected to the EMU so that we could monitor and alert on the run-cycles of the generator. Our transfer switch did not have these capabilities, but you could apply the same configuration we used for out generator. The EMU has built-in alerting as well as the ability to send SNMP traps. - Chris On Fri, May 14, 2010 at 1:59 PM, Tom Beecher <tbeecher@localnet.com> wrote:

I've found the Weathergoose II to be a good general-purpose SNMP monitoring device. They also have something called the Relaygoose which can accommodate more inputs and trigger relays as well. http://www.itwatchdogs.com/p_product_detail.php?pnum=1 -Nick

We have some old NetBotz (now part of APC) in our NOC, and ours have dry contact ports, so we hooked one up to our transfer switch. Works like a champ. -- Chris Adams <cmadams@hiwaay.net> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
