The Siemens 6ES5 470-4UA11 is a high-precision analog output module engineered for the Simatic S5-135 and S5-155 PLC systems. This unit provides 8 channels of analog signal conversion, supporting both voltage (10 VDC) and current (0-20 mA) output formats. It is primarily deployed in closed-loop control applications, such as modulating valve actuators, variable frequency drives, and process heating controllers within oil refineries, chemical processing plants, and power generation facilities. By ensuring precise signal transmission to final control elements, this module serves as a critical component in maintaining process stability and reducing costly process interruptions.
This module is designed for industrial automation environments requiring reliable analog signal output, including:
| Model | 6ES5 470-4UA11 |
| Brand | Siemens |
| Product Series | Simatic S5 |
| Output Channels | 8 |
| Signal Ranges | 10 VDC or 0-20 mA |
| Operating Temperature | 0 to 55 degC |
| Power Supply | Simatic S5 backplane bus |
Is this module compatible with the S5-115U series?
No, the 6ES5 470-4UA11 is specifically designed for the S5-135 and S5-155 series backplane architecture.
Does this module require external power for the outputs?
The module draws its primary operating power from the S5 backplane, but ensure your field devices are correctly wired for the selected 10 VDC or 0-20 mA output mode.
