2TLA020070R5600-JOKA

Overview

The Jokab Safety 2TLA020070R5600 is a safety relay module designed for industrial machinery protection. It operates on a 24 VDC control voltage and features two safety-rated make contacts (2 NO) with positive opening mechanism. The unit provides one auxiliary contact (1 NC). It supports diagnostic functions including coil monitoring and contact welding detection to ensure reliable operation. Designed for DIN rail mounting, the device complies with international safety standards such as IEC 61508 and ISO 13849-1, offering Performance Level e (PL e) and Category 4 according to EN ISO 13849-1.

Feature Summary

• Positive opening mechanism ensures safe contact separation during fault conditions
• Integrated coil monitoring and contact welding detection for continuous self-diagnosis
• Compact modular design suitable for standard DIN rail installation in control cabinets

Applications

• Safety interlocking for machine guards and access doors
• Emergency stop circuit implementation in automated production lines
• Two-hand control device integration for press operations

Procurement Notes

Verify the specific suffix and revision code against the manufacturer's current product catalog to confirm functional specifications. Ensure compatibility with existing 24 VDC control systems and required safety integrity levels before procurement. Cross-reference the part number with official ABB Jokab Safety documentation to validate performance ratings and certification status.

Selection Notes

Select this component when a compact safety relay with integrated diagnostics is required for PL e applications. Verify that the available make and make/transfer contacts meet the specific logic requirements of the safety function. Confirm that the 24 VDC operating voltage aligns with the plant's control power supply infrastructure.

Part Context
