Siemens 6FM1470-4BA20 SIMATIC S5 Display Module

This display module provides operator feedback for SIMATIC S5 control systems. It shows process values and system status on a built-in alphanumeric screen. Therefore, this component suits applications requiring local monitoring without an HMI panel.

Physical Dimensions and Weight Specifications

The Siemens 6FM1470-4BA20 occupies one standard slot in the S5 rack. Its housing measures 233 mm in depth for backplane connectivity. The module weighs approximately 0.42 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Siemens 6FM1470-4BA20 provides a 48-pin front connector for field wiring. A 20-pin backplane connector supplies power and data from the CPU. The front panel carries a 4-line alphanumeric LCD display with 20 characters per line. Hence, operators can read process values directly from the rack.

Component Count and Display Technology

This display module contains one main board with a character generator chip. The board holds 8 KB of display buffer memory for screen data. You will also find contrast adjustment potentiometer on the front panel. An onboard microcontroller handles communication with the S5 backplane.

Energy Storage and Power Consumption

The Siemens 6FM1470-4BA20 draws 90 mA from the 5V backplane supply. A small capacitor maintains display content for 50 milliseconds during power dips. This storage prevents screen flicker from brief voltage drops. The module requires no battery for normal operation.

Operating Conditions and Visibility

The display operates in temperatures from 0°C to 55°C. Users can adjust contrast for optimal viewing under various lighting. The module supports both German and English character sets. This flexibility suits international machine builders.
