Input Characteristics and Performance

Each input channel on the 6ES5482-7LA11 draws 8 mA nominal current at 24 V DC. The module provides a response time of less than 5 ms for fast signal capture. Furthermore, it features optoelectrical isolation between inputs and the backplane bus. This design protects the controller from electrical noise and voltage spikes. In addition, LED indicators on the front panel display real-time status for each input channel.

Output Characteristics and Protection

The 6ES5482-7LA11 offers 16 output channels with a current capacity of 0.25 A per channel. Each output includes short-circuit protection to prevent damage from wiring faults. Moreover, the module’s protection circuits automatically reset after fault removal. Output status LEDs provide visual confirmation of each channel’s state. Consequently, troubleshooting becomes faster and more efficient.

Physical Characteristics and Installation

Weighing approximately 0.55 kg, this module fits standard S5 rack configurations. Its compact design occupies a single slot within the chassis. The module uses screw terminal connections for secure and straightforward field wiring. The front panel provides clear labeling for easy channel identification. Furthermore, users can install the 6ES5482-7LA11 quickly without special tools.

System Compatibility

This module works with SIMATIC S5-115U, S5-135U, and S5-155U PLC systems. It communicates with the CPU through the S5 backplane bus. Users can connect this module directly to field devices such as pushbuttons, sensors, and solenoid valves. The mixed I/O configuration reduces the number of modules needed for control tasks.
