Siemens 6ES5470-4UA11 Analog Output Module

The 6ES5470-4UA11 generates analog output signals for Siemens SIMATIC S5 systems. This module controls valves, drives, and other analog field devices. Its rectangular frame measures 232 millimeters in width. The module height reaches 210 millimeters exactly. Depth stays at 155 millimeters. You will find this unit weighs approximately 0.88 kilograms. Therefore, installation requires sliding the module into a standard S5 rack slot. One 20-pin front connector handles all field wiring connections.

Physical Layout and Connectors

The front connector accepts wires up to 16 AWG gauge. Each channel uses two terminals for signal and common return paths. A green LED illuminates when the module receives power from the backplane. Two guide rails secure the module firmly in the rack. You can remove the front connector without disconnecting the module from the backplane.

Internal Design and Energy Storage

The 6ES5470-4UA11 contains exactly 248 discrete components onboard. An 820 microfarad capacitor bank filters noise from the internal power supply. Eight independent output drivers generate the analog control signals. Each driver includes programmable gain and offset adjustment. A 12-bit digital-to-analog converter converts logic commands to analog values. The module also provides short circuit protection on every output channel.

Operational Performance

This analog output module generates voltage signals from 0 to 10 volts. It also produces current signals from 4 to 20 milliamperes. Moreover, the unit drives proportional valves, VFDs, and chart recorders. You can configure each output channel independently using PLC software. The module updates all outputs simultaneously for synchronized control. Eight green LEDs indicate active channels during normal operation. Consequently, you achieve precise analog control for process applications. Siemens designed this module for SIMATIC S5 automation platforms. Its shielded design rejects electromagnetic interference effectively.

In summary, the 6ES5470-4UA11 delivers precise analog output functionality. Use this module for flow control, pressure regulation, or speed control. It provides eight output points in a single slot design. Order this analog output module for your Siemens S5 system.
