Technical Specifications

Output Protection and Isolation

The 6ES5458-4UA11 module features relay outputs that provide complete galvanic isolation between the field side and the backplane bus . This isolation protects against electrical noise and voltage transients. The relay contacts handle a wide voltage range from 5 to 30 V DC, offering flexibility for various loads. Furthermore, the module includes LED indicators for each output channel.

Switching Performance and Applications

This output module handles 16 channels switching at up to 10 Hz for resistive loads. The 6ES5458-4UA11 also supports inductive loads up to 2 A with appropriate suppression . Its relay outputs allow mixing of different load voltages within the same module . Users can connect this module to motors, valves, and other actuators. The robust relay construction ensures long service life.

Physical Characteristics and Installation

Weighing approximately 0.55 kg, this module fits standard S5 rack slots. It uses screw terminal connections for secure and straightforward field wiring. The module draws minimal power from the backplane bus. Its front panel includes clear labeling and LED status indicators.
