SIEMENS 6ES7405-0DA01-0AA0 PS 405 POWER SUPPLY, 24VDC, DC 5V/4A

Got it, you're asking about the Siemens 6ES7405-0DA01-0AA0 PS405 power supply module.

This is a very similar model to the one I just described, but with a slightly different part number. Here are the key details:

- Model Number: 6ES7405-0DA01-0AA0
- Product Name: SIMATIC S7-400 PS405 Power Supply, 24VDC
- Input Voltage: 24 VDC
- Output Voltage: 5 VDC
- Output Current: 4 A
- Mounting: Designed to install directly into an S7-400 rack system

The main differences between this 6ES7405-0DA01-0AA0 model and the previous 6ES7405-0DA00-0AA0 are:

1. The part number suffix - 0DA01 vs 0DA00
2. There may be minor manufacturing or component revisions between the two models
3. The functionality and specifications are otherwise identical

Both the 0DA00 and 0DA01 versions of the PS405 power supply provide a 24VDC input and 5VDC/4A output to power the SIMATIC S7-400 PLC system.

They share the same compact design, diagnostic LEDs, short-circuit/overload protection, hot-swap capability, and S7-400 system bus integration.

So in summary, the 6ES7405-0DA01-0AA0 is simply a slightly updated model of the S7-400 PS405 24VDC/5VDC 4A power supply module, but the core functionality remains the same between the two part numbers.
