Siemens 6ES5470-8MB12: Isolated Analog Output Module for S5 Systems

Meet the Siemens 6ES5470-8MB12, a high-performance analog output module from the SIMATIC S5 series. This module provides two electrically isolated current output channels, each delivering ±20 mA. Moreover, it is specifically designed for use with S5-90U, S5-95U, S5-100U, ET 100U, and ET 200U controllers. Consequently, it offers precise and reliable command signal generation for actuators like valves and drives.

Detailed Technical Specifications

The 6ES5470-8MB12 module ensures accurate signal conversion with robust galvanic isolation. Below are its precise technical parameters for correct system integration.

Core Functionality and Application

This module converts digital values from the CPU into precise analog current signals. Therefore, it directly controls proportional valves, I/P converters, or variable-speed drive references. Additionally, its channel isolation prevents ground loops and protects the controller from electrical noise in the field.

The ±20 mA output range provides flexibility for both unidirectional and bidirectional control applications. Furthermore, for a complete and protected control loop, ensure proper safety measures. For instance, integrating a RMS-TSG-TZ-C Static Trip device can protect the module’s power supply circuit.

Engineered for Stable and Precise Signal Generation

Choosing the Siemens 6ES5470-8MB12 ensures stable analog output performance for your legacy S5 system. Its isolated design guarantees signal integrity in electrically noisy industrial environments. Ultimately, this module is a reliable and essential component for accurate closed-loop process control.
