550ACD Electro Pneumatic Converter OEM Order
An OEM batch of the miniature 550 series built with the DIN 43650 connector, the plug-in termination used across European-built plant.
Controlair Type Transducer 550-A-C-D: 4-20 mA input, 3-15 psig output, DIN 43650 connector, customer branded
What The Customer Needed
The customer builds packaged equipment wired entirely with DIN plugs. A conduit or terminal-block instrument would have forced a wiring change on their assembly line.
How It Was Built
The D field of the 550 coding system selects the DIN 43650 connector, so the termination was specified at the order stage rather than adapted afterwards, and the units arrived matching the customer's harness.
What The Photographs Show
Connectors were fitted and gasket-checked before calibration, then the batch was tested with the plugs in place. The photographs show the units in rows with their connectors fitted, which is how they shipped.





How It Finished
Instruments that plugged straight into the customer's existing harness, under their own label.
