Information About 3SK1211-1BB40
The 3SK1211-1BB40 is part of the Siemens SIRIUS 3SK series and is engineered to serve as an output expansion module for basic and standard safety relays. Its main function is to extend the number of actuated contacts without adding complexity to the base unit. This device includes 4 safety-related N.O. contacts and one signaling N.C. contact, supporting a wide range of safety applications such as emergency stop circuits and protective door monitoring. Operating at 24 VDC, it is optimized for DIN rail installation in control panels with limited space. The enclosure has a protection rating of IP20, ensuring secure operation in controlled environments.
Key Features:
- Relay Output Expansion Module: Increases the number of output contacts for safety relay systems.
- 4 N.O. Safety Outputs + 1 N.C. Signaling Output: Provides multiple actuation options with reliable switching.
- 24V DC Control Voltage: Compatible with most industrial control systems using standard safety logic.
- DIN Rail Mounting: Ensures quick installation and secure positioning within control cabinets.
- Compact 22.5 mm Housing: Ideal for space-constrained environments where panel space is limited.
- Screw-Type Terminal Connections: Secure and robust wiring solution, easy to install and maintain.
- No Input Channels: Acts purely as an expansion device controlled by upstream logic.
- IP20 Protection Rating: Suitable for use inside electrical enclosures.
- Part of the Siemens SIRIUS 3SK Series: Compatible with standard Siemens safety relay units for seamless integration.
- Reliable Relay Release Circuit: Provides dependable disengagement for connected outputs in safety scenarios.
The 3SK1211-1BB40 facilitates flexible safety design by expanding outputs without complicating wiring or logic.
