Discrete Inputs?

Post by datamike »

What's the purpose and usage of the discrete inputs?

Thanks!

One thing I know they can be used for is a float switch.

Ahh, so like a low-voltage input from an external device then? I am slowly starting to figure out the 460. I think it'll be easier once I have everything wired up. Right now I am working on welding up the brewstand.

Thanks!

more like the BCS sends out a 5v signal and can tell if the float switch is open or closed by looking for the 5V ref. voltage.. It can also be used to turn things on manually
but it a round about way .not really how they are meant to be used . I can explain more later. I have to run..
good luck on the stand/ brewery !

there is a page on the wiki .. you find it under the documentation page.

Discrete Inputs (Dins) are available for switches, push buttons, etc. They are also rated at +5VDC. To assert a Din, connect the Din terminal to the +5VDC terminal (presumably through a switch). To deassert the Din, simply disconnect the Din terminal, as there is a weak pulldown resistor that will pull the Din to ground.

This is the only use of a DIN I can find so far in the documentation :

DINS can be used as an exit condition to go to a different or the next state.
