    If the customer is happy and you're making money the best policy is "don't rock the boat". Let them stay with the garden variety.

    The machine is currently operating @ 140 hrs/week and I guess we have been losing a relay on an average of 1000 hrs. We have used these relays for years on AC solenoids and failures have been few and far between. The problem is with the DC inductive load.
    Funny you should mention the IXYS devices as I recently downloaded datasheets of some of their other SSRs....I could not find a price somehow but that part number worked when I Googled (don't know what I was searching for before). $5 is Digikey's single-piece price which is very reasonable.

    Problem remains though that these big plants prefer garden variety off-the-shelf components to minimize downtime....but they don't want to stock spares...aaarrrggghh!
