Digital Timer
(OP)
I'm looking for a digital timer that will function as two seperate timers. In other words, has two independent outputs with independent settings. Is such a timer available?

RE: Digital Timer
Is it a ready-to-use unit you are looking for? Or how to build such units?

You could also use a "programmable relay", like Siemens' LOGO! They can offer you up to four digital timers in one device. Separately settable and lots of flexibility.

RE: Digital Timer
I was also considering a programmable relay like you suggested. I suppose one programmable relay would be cleaner and more cost effective, and flexible than two individual timers.
As far as programmable relays go, I know there are several out there; the logo, Teco makes one, I think Omron does also. Is there one that stands out above the others, in your opinion?

RE: Digital Timer
The LOGO! modules are excellent, although it is a long time since I used one. It was pretty straightforward to program, and the LOGO! was the first unit of its type that I had worked with.

So, if you have a few very simple analogue tasks that switch on/off at a certain temperature or pressure or if you need a pulse train with variable duty cycle as a function of an analogue value, you can use them. You can also have a limited "recipe" function by using two or three inputs to select and activate different blocks in the program. Two inputs let you have four "recipes" and three can give your eight different set-ups. But not sure if there are enough free blocks for that.

GE Grasslin, presumably among others, produce programmable timers with two and more channels that can be set to switch independently. GE Part nos 666190 or 666191 should be suitable (not that i'm trying to plug GE products, its just that this is what I am most familiar with).
RE: Digital Timer
Once Siemens Germany invested in the LOGO! mass production, they brand labeled it to Idec to help offset the costs. They sell enough of the S7-200's to keep it viable without having to brand label it.

You may use a DL05 DirectLogic miniature plc from automationdirect. The price of 2 timer relays is about as much and you can program any variable operation you choose as well. It's $99 and that is hard to beat considering that a timer relay could cost $40 or more.

Thanks for all the responses.

About how much did that Horner set you back?
