This morning I am traveling to Melbourne Australia for a few days. While there I will be talking to one or two of end users about design - electro mechanical design, of our SCD5200 IO terminal assembly. The unique SCD5200 design has been stable since it's introduction 10 years ago, thereby begging a 'why change it ?' from our team as well as our end users.

SCD5200 remote terminal units are compact with a reasonably high density hard wired IO. The mix of IO type {Discrete,Analog} and DC/AC voltage levels {24,48,129} provides convenience but needs special design consideration.

The potential design change, would be based on a requirement to increase the insulation thickness of the end user wiring connecting to the assembly. No it's not about increased voltage levels, nor about an increase in accuracy, not current rating nor actual wire cross section.

Ever since the ability to quickly compute and the creation of electronic configurations, we've seen companies struggle with trying to quickly develop consistent configurations from a top down logical design basis.  The advent of object oriented systems has enabled configuration to be partitioned in uniquely named environments.  If only the real world would comply with the lovely abstract designs we have on the computer screen.
