SIEMENS 6ES7405-0DA02-0AA0 SIMATIC S7-400 PS405 POWER SUPPLY, 24/48/60V DC, 4A

Okay, got it. You're asking about the Siemens 6ES7405-0DA02-0AA0 SIMATIC S7-400 PS405 power supply module.

Here are the key details on this particular model:

- Model Number: 6ES7405-0DA02-0AA0
- Product Name: SIMATIC S7-400 PS405 Power Supply
- Input Voltage: 24 VDC / 48 VDC / 60 VDC (selectable)
- Output Voltage: 5 VDC
- Output Current: 4 A
- Mounting: Designed for installation in an S7-400 rack system

The main difference between this 6ES7405-0DA02-0AA0 model and the previous ones is the expanded input voltage range.

While the prior PS405 models were 24VDC input only, this version supports selectable input voltages of 24VDC, 48VDC, or 60VDC.

This added flexibility allows the PS405 power supply to be used in a wider variety of SIMATIC S7-400 applications, where the input power source may vary.

Otherwise, the core functionality remains the same - it provides a regulated 5VDC/4A output to power the S7-400 CPU, I/O modules, and other connected components.

It still has the compact rack-mountable design, diagnostic LEDs, short-circuit/overload protection, hot-swap capability, and S7-400 system bus integration.

So in summary, the key difference for the 6ES7405-0DA02-0AA0 PS405 is the multi-voltage 24/48/60VDC input range, allowing for more flexibility in S7-400 power supply applications.
