Digital Logger Power Switches

Hi Bob,

Just trying to work out the device requirements for our school observatory.

It will have two robotic mounts both running ACP Scheduler. Each PC/mount will have 3 devices connected to AC power and 3 connected to DC power.

I was planning on using Digital Loggers Universal Input Smart Power Switch for AC and a Digital Loggers Smart DC Power Switch for DC. Each of these switches have 8 outlets.

Would I be able to have two PCs, each running ACP, talking to both switches simultaneously to power on and off items as required? I am presuming this would be done with scripts. Does each switch have its own IP and the script call on the specific outlet at that IP to turn on/off? Would two PCs be able to access the IP simultaneously? Scripting is a whole new language for me, so please excuse me if I'm on the wrong track here.

(I'm hoping to avoid adding another set of switches to the budget...)

Partial answer: you probably could simplify your design by having only one AC controller (8 channels), then adding very inexpensive AC-switched relays to 3 of its outputs to get DC control (http://www.digital-loggers.com/ac.html). Then all AC and DC are controlled by one main controller (http://www.digital-loggers.com/lpc.html) and thus one IP address.

Thanks for there reply Eric,

We use 240VAC power in Australia - unfortunately the AC-switched relays can only cope with up to 140VAC. Nice suggestions though.

The 240V-driven relay should be easy to find...the chaining aspect is the main idea.

Or more simply, do what I do in my observatory: just plug the DC power supplies into the web AC controller, and control the generation of DC rather than relay-switching it.
