Siemens 6ES5484-8AG11 Analog Input Module

This Siemens analog input module converts field sensor signals into digital process data. The Siemens 6ES5484-8AG11 handles eight differential input channels for precise measurement tasks. Its high-resolution conversion ensures accurate representation of physical variables. This module supports both voltage and current signals from various transmitters. The Siemens 6ES5484-8AG11 integrates seamlessly into SIMATIC S5 rack systems. Its design emphasizes measurement precision and noise immunity in industrial environments.

Input Ranges and Conversion Specifications

This module accepts voltage ranges from 0 to 10 V and -10 to +10 V. It also handles current signals from 0 to 20 mA and 4 to 20 mA. An integrated 12-bit analog-to-digital converter provides 4096 count resolution. The conversion time per channel reaches approximately 25 milliseconds. The Siemens 6ES5484-8AG11 offers a measurement accuracy of ±0.5% of full scale. Input impedance measures 10 MΩ for voltage inputs for minimal loading. Current inputs present a load impedance of 250 Ω for standard loop operation.

Physical Dimensions and Electrical Characteristics

The module measures 232 mm in height and 25 mm in width. Its overall depth reaches 160 mm including the front connector. This unit weighs approximately 0.5 kilograms without packaging materials. The housing supports standard 35 mm DIN rail mounting for quick installation. The Siemens 6ES5484-8AG11 draws a maximum current of 150 mA from the backplane. A 20-pin front connector handles all signal and power connections. This connector accepts solid or stranded wires from 0.5 mm² to 2.5 mm². An internal filter capacitor of 10 nF suppresses high-frequency noise on each input.

Isolation and Status Indication

Each input channel features optocoupler isolation for electrical protection. This isolation withstands 500 V AC between the field and logic circuits. A common-mode rejection ratio of 80 dB minimizes interference from ground loops. The module provides a front-panel LED for supply voltage status. Eight additional LEDs indicate the activity of each individual input channel. The Siemens 6ES5484-8AG11 includes a built-in reference voltage source for calibration. This reference ensures stable operation across temperature variations.
