Siemens 3TK2823-1CB30 Safety Coupler

Product Dimensions：

The Siemens 3TK2823-1CB30 is a specialized Safety Relay from the SIRIUS family. It is specifically designed as a Press Control Relay, intended for use in safety circuits for mechanical and hydraulic presses, as well as other high-risk metalworking machinery.

Product Detailed Description

The 3TK2823-1CB30 is a dual-channel safety evaluation unit that monitors and controls safety-related signals. It is a critical component in ensuring that dangerous movements are stopped immediately when a safety condition is breached. It is primarily used to monitor Two-Hand Control Stations, ensuring that an operator must use both hands simultaneously to initiate a press stroke, thereby keeping their hands away from the danger zone.

Technical Parameters

Product Advantages

• Certified Safety: Complies with the highest safety standards for press controls (Type III C according to EN 574), making it suitable for hazardous industrial environments.
• Simultaneity Monitoring: The relay requires both inputs to be activated within 0.5 seconds of each other; if one button is tied down or fails, the relay will not trigger, preventing bypass attempts.
• Compact Design: The slim housing saves valuable space within the electrical control cabinet.
• High Diagnostic Coverage: Integrated LEDs provide clear status indication for power, input channels, and fault conditions, significantly reducing troubleshooting time.
• Durability: Engineered for high switching cycles, typical of fast-paced production lines and stamping presses.

Important Considerations (Precautions)

• Cross-Circuit Monitoring: This module is designed to detect cross-circuits between the monitoring channels. Ensure wiring follows the manufacturer’s schematic to utilize this safety feature.
• Manual Reset: Depending on your safety logic, ensure that the reset function (automatic or monitored manual) is configured according to the risk assessment of the specific machine.
• Terminal Torque: Use the specified torque for screw terminals to avoid loose connections, which can lead to intermittent safety trips or overheating.
• Surge Protection: While the unit operates on 24 V DC, it is recommended to use a stable, filtered power supply to prevent electronic damage from industrial voltage spikes.

Product Applications

The 3TK2823-1CB30 is a “gold standard” for specific hazardous applications:

• Metal Stamping Presses: Controlling the stroke of mechanical or hydraulic presses via two-hand stations.
• Cutting & Shearing Machines: Ensuring the operator’s hands are clear before a blade or shear is activated.
• Assembly Workstations: Used in pneumatic presses for small-part assembly where hand-trapping hazards exist.
• Safety Gate Monitoring: Though specialized for two-hand control, it can be integrated into broader safety systems requiring dual-channel evaluation and SIL 3 compliance.
