550X Electro Pneumatic Transducer Order
An order covering several 550 code combinations, chosen for a mixture of panel, rail and valve-mounted positions.
Controlair Type Transducer 550 series miniature electronic pressure regulators, mixed codes
What The Customer Needed
One site, three mounting situations and two different electrical standards. Buying three different instruments would have meant three sets of spares.
How It Was Built
The 550 coding system covers all of it from one series: the input, the output, the electrical connection and the options are separate fields, so the instruments differ only where they have to.
What The Photographs Show
Mounting kits were matched to each position, the DIN rail kit for the cabinet assemblies and the pipe mounting kit for the valve-mounted units. The photographs show the mixed batch on the bench before separation.





How It Finished
One series covering three mounting situations, with a single spares holding behind it.
