Siemens SIRIUS 3SK1122-2CB41 Safety Station Basic Unit with Short Delay

Product Positioning

The 3SK1122-2CB41 is a basic unit in the Siemens SIRIUS 3SK1 Advanced series, featuring a short time delay function of 0.05 to 3 seconds, suitable for safety circuit designs that require short-delay power-off protection.

Core Product Advantages and Features

Short delay time setting

The delay time can be adjusted from 0.05 to 3 seconds, making it suitable for delayed power outage applications that require rapid response.

Instantaneous plus delayed dual output

The electronic system provides two sets of instantaneous enable outputs and two sets of delayed enable outputs to meet different timing control requirements.

Spring-type terminal quick connection

Using spring-type terminals, wiring can be completed without screws, saving more time during installation.

Modular expansion architecture

Input or output expansion modules can be added via device connectors to flexibly build a complete security chain.
