I need to know the exact pin configuration for the back panel 5 pin DIN power supply plug for a Dionex UI20 Interface. Please note it is not in the Dionex UI20 Manual.

Here's the information from our UI20:

Looking at the end of the PLUG, with the notch at the top, the DIN standard pin numbering is 1, 4, 2, 5, 3 going counter-clockwise i.e. starting on your left. It’s done that way so the pin numbers stay the same regardless of whether the DIN connector has 3, 5, 7 or 8 pins.

UI20 pinout:
pin 1 is common
pin 4 is -12V
pin 2 is ground (tied to common)
pin 5 is +12V
pin 3 is 5V

We verified this by opening up the UI20 and taking the readings directly from the socket, with the PS plugged in.

The power supply is made by ITE, model number UP02513010. Lots of search hits on that model, at widely varying prices. Note that it is available with various connectors (DIN, mini-DIN) and different pinouts!

Input: 100-250VAC, 50/60Hz, 0.9A. Output: +5VDC @ 3A, +12VDC @ 0.5A, -12VDC @ 0.2A.

This appears to be the same model, with the same pinout:
