In Control

I am posting our Christmas arrangements a bit earlier this year. Our Boston office will be closed from now until December 22, while we all get together here in Melbourne for somewhat extended celebrations (and some serious work!). The Boston office will again be closed December 25 through January 1.

Our Melbourne office closes December 19 through January 4, re-opening Monday January 5.

Between now and December 19 all orders will be shipped out of Melbourne. From the December 19 through January 4 there will be no order processing.

I need 4 isolated outputs operating on 24V. Outputs will be changing state 24 x 7 for many years. My thoughts were opto isolator transistor drivers.

The intended controller is a MS120.

This controller is going into an industrial situation and will be critical to monitoring production. Do you have any reliability recommendations?

Hi Peter,

You didn't mention what the isolated outputs are to drive. Assuming its something with a bit of power, I suggest you look at DC solid state relays. Google for "DC solid state relays"

As to reliability, the most important things are:
