This equipment gets mounted in various different industrial settings where the system control bus can be 120V, 240V AC or 48V, 125V, 250V DC. So far we've pushed the relatively few 48V DC customers to rewire their systems for 120V AC. For the customers that have 250V DC, that's not really a favorable option for them. The DC customers usually derive the control bus power from a battery bank that fills a whole room. The suggestion of changing to something thats not battery backed is not usually well received= .. -Denny --=20 http://www.piclist.com/techref/piclist PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
