Power supply

The original power supply is roughly:

  • 12V in?
  • Dual channel
  • Power-one DGP12U5D5, WTT250IG
    • Outputs +/- 5V
    • Is the -5V rail used?
    • Seem to output 5.3 or 5.4V
  • LM317
  • So basically: 12V DC is converted to just above 5V. Then a linear regulator smooths the last remaining bit down to 5V


Weidmüller-4 Wire color Volt Note
1 Blue 5.11 Ground?
2 Green 0 -5V?
3 Black 0 -5V?
4 Orange 10.85 +5V?
DB9 Wire Weidmüller-8 Volt
1 Yellow 2 0V
2 Blue 2 0V
3 Gray 4 0V
4 Black 4 0V
5 Red N/C
6 Green 1 5.15V
7 Violet 1 5.15V
8 White 3 5.05V
9 Brown 3 5.05V

Weidmüller BL series 3.5 mm connectors. Suggested connectors:

  • Black female inline, BL series
    • 4: 1615690000, BL 3.5/4 SN SW
    • 4 backorder alt: 1638800000‎

Camera

  • DC-12: 12 cm x 12 cm
  • DC-5: 5 cm x 5 cm, less expensive

10 lp/mm spatial resolution in contact mode. Magnification allows for spatial resolution of up to 50 lp/mm. The 20 μm nominal focal spot and up to 5X additional geometric magnification

Specs

  • Window: 0.01” beryllium
  • Resolution: Up to 50 lp/mm (10 lp/mm contact mode)
  • 10-35 kVp @ 300 μA
  • <20 μm spot size

Perkin-elmer_xrd-1640_an19-ets-lp

"The MX-20 had an Perkin Elmer panel sensor with parallel output to an SCSI PC interface board. It can do medium sized boards, up to 10" x 12"...The P-E sensor that came with my MX-20 was not it's original sensor. My MX-20 was non-digital, just a film based one (or phosphor plate based). The P-E had a low voltage differential, parallel, output that was sent through a cable to a PCI frame capture board. The board (made by Perkin Elmer) looked like a SCSI interface to the PC. The sensors are available on eBay, sometimes for a good price, but I've not seen a complete system, sensor, power supply, cables, interface card, and software, in a long time. A sensor is on eBay now, see"
