Thanks to all that responded.
The PLC is a Crouzet Millenium 2, the second generation of this line. I work for an electrical distributer and Crouzet is one of our lines. I design and program automation controls systems as a applications engineer.
There are a couple of neat things about this unit. First, it has a built in 4 line baclit LCD that can be used for simple operator interface. It also has the ability to dedicate some of its DC inputs to monitor an analog signal, albeit with only 8 bits of resolution. The relay outputs are fairly substantial handling 8 amps each.
If it has a down side, it would be the programming language. It uses a graphical format with small symbols for all the common functions. You place them on the page and draw lines representing wires inbetween all the inputs and outputs. For small programs its fine, but when they get larger it gets kind of messy, but it wasn't hard to learn, and the simulation mode works well for debugging purposes.
I am familiar with Automation direct, did a lot of work with there 405 series in a previous job, they are good controllers too. This unit was from an engineering evaluaiton kit we had, thats where the row of switches and potentiometer came from.
