Product Precautions
- Siemens 6ES5470-4UC12 converts controller output values into continuous process signals. Its voltage and current connections require the corresponding load and reference-potential arrangement.
Product type: Analog output module
Output channels: 8
Signal ranges: 1–5 V and 4–20 mA
Output channels: 8
Signal ranges: 1–5 V and 4–20 mA
The 6ES5470-4UC12 belongs to the SIMATIC S5 470 analog output family. Its eight channels provide 1–5 V and 4–20 mA in parallel, with a nominal command representation of 0 to 1024 units. This range differs from the 470-4UA and 470-4UB variants, so the complete order code matters when preserving an existing process scale.
The output-value representation is 12-bit two's complement. The common 470 specification gives a delay of no more than 1 ms from data transfer to the analog output, and an operating error limit of ±0.6% over 0–60 °C. The eight outputs share the external reference Mext; isolation does not mean separate isolation between individual channels.
For voltage operation, the load resistance must be at least 3.3 kΩ and output current must not exceed 3 mA. Current-output loads must not exceed 300 Ω; the maximum no-load voltage is 18 V. Keep total capacitive loading below 100 nF and check the front-connector assignment, module enable and installed address before reconnecting process wiring.

-
Process setpoints
Use the 1–5 V outputs for compatible process interfaces while preserving the controller scale and reference potential. -
Current-loop commands
Use the 4–20 mA connections with loads within 300 Ω and verify the receiving device range. -
S5 maintenance
Retain the complete 4UC12 order code, rack arrangement and existing program addressing during replacement. -
Loop verification
Check command-to-output response at controlled test points before releasing the connected process.
Prepare 6ES5470-4UC12 against the installed configuration and applicable Siemens instructions. Plan isolation and the resulting interruption of system operation before replacement.
Isolate the process
Place the machine in a safe state and isolate power before handling the module or front connector.
Preserve the variant
Use the complete 6ES5470-4UC12 reference; other 470 suffixes have different output ranges.
Check the load
Keep voltage loads at or above 3.3 kΩ and current loads at or below 300 Ω.
Respect the common reference
Check Mext and the front-connector wiring. The eight outputs are not individually isolated channels.
Retain configuration
Record the address and output scaling before removal; verify them against the installed S5 application.
Test under control
Apply controlled output commands and confirm the receiving equipment response before restoring normal operation.
