Siemens 6ES5482-7LF21 Digital Input/Output Module

Combined Discrete I/O Solution for SIMATIC S5 Systems

The 6ES5482-7LF21 digital input/output module provides a compact combination of 32 inputs and 32 outputs for the SIMATIC S5 automation platform . This integrated design saves valuable rack space while delivering versatile discrete I/O capabilities. It suits applications requiring both input sensing and output actuation within a single module. Consequently, this module simplifies system configuration and reduces hardware costs.

Input and Output Specifications

This module accommodates 24 V DC input signals with a nominal current of 8 mA per channel. The inputs respond within a typical 5 ms delay for accurate signal capture. On the output side, the 6ES5482-7LF21 delivers 24 V DC at 0.5 A per channel for reliable actuator control. Furthermore, each output includes short-circuit protection for enhanced system safety.

Physical Characteristics and Installation

The 6ES5482-7LF21 weighs approximately 0.55 kg and fits standard S5 rack slots. It draws 150 mA from the 5 V DC backplane bus and dissipates 7.5 W of power. The module also features LED indicators for each channel, enabling quick field diagnostics. Furthermore, it includes screw-type connectors for straightforward and secure wiring.
