I've used a few different smart relays so I figured I'd mention something.
The Telemecanique's work pretty well and are fairly straightforward to program, get a manual if you're not going to program it on your pc. I didn't get a manual and was able to figure out how to program it using the help feature on the computer.
I have a Teco, they're cheap and fairly easy to program on a pc, but I don't care for their manual and all the Chinese instructions. The one I'm using has been running my sprinkler system for a couple years now with no issues.
The AB Pico is too high priced for my tastes, it's probably $30-40 higher than a comparable smart relay.
It seems like most smart relays are the same aside from different badging, so paying extra for AB doesn't really make sense to me...
Last of all, if you don't need a screen on it, and are looking for something with a few more features, I wouldn't hesitate to take a look at the Click from Automation Direct. I've got a couple here at home I've tinkered with to see if I like 'em and they seem like a great product for the price. Very easy to program, Automation Direct has a great instruction manual online for building a program. I'll use these in a heartbeat, when I come across a project that could use them. Since they're so inexpensive, even if you have a project that a smart relay could handle, these might be worth taking a look at.
