Description

ABB 2TLA020070R4600 Programmable Safety Controller

The ABB 2TLA020070R4600 (also known by the model name Orion1-4-14-120-E) is a high-performance Type 4 Safety Light Curtain. It is part of the ABB Jokab Safety product line, specifically designed to protect personnel by detecting fingers, hands, or bodies entering hazardous zones around machinery.

Product Detailed Description

The Orion1 Extended series is an optical safety sensor consisting of an emitter and a receiver. It creates a vertical detection field using infrared beams. The 14mm resolution of this specific model makes it suitable for finger detection, providing the highest level of proximity protection. This “Extended” version includes integrated functions like Muting and Blanking, which allow for more complex automated workflows where materials must pass through the light curtain without stopping the machine.

Technical Parameters

Product Advantages

• Integrated Functions: Supports Muting (temporary bypassing for material entry) and Blanking (ignoring fixed objects in the field), eliminating the need for an external control module for these tasks.
• Easy Alignment: Features a built-in Alignment Tool and local LEDs that change color and flash to indicate the quality of the optical alignment between the emitter and receiver.
• Robust Safety: As a Type 4 device, it meets the highest international safety standards, making it suitable for high-risk applications (SIL 3 / PLe).
• Minimal Dead Zones: The optical windows extend close to the edges of the housing, allowing for seamless protection when installed in tight spaces.
• No Separate Controller Needed: The OSSD outputs can connect directly to safety relays or safety PLCs (like the ABB Pluto).

Important Considerations (Precautions)

• Safety Distance: The light curtain must be installed at a specific calculated distance from the hazard (based on the formula S = K \times T + C). Because this is a 14mm resolution unit, it can be mounted closer than coarser resolution models.
• Reflection Hazards: Avoid placing the light curtain near highly reflective surfaces (mirrors, polished metal), as the infrared beams may bounce around an object, failing to detect an intrusion.
• Environmental Factors: While IP65 rated, heavy steam, dense smoke, or high-pressure washdowns can interfere with the optical beams. Ensure the lenses are kept clean.
• Wiring: Since this is the Extended model with muting/blanking, ensure you follow the specific wiring diagrams for the 12-pole connectors to avoid configuration errors.

Product Applications

The 2TLA020070R4600 is ideal for high-precision safety requirements:

• Robotic Cells: Protecting the perimeter of robot workstations where human interaction is frequent.
• Pharmaceutical Packaging: Detecting fingers near high-speed capping or bottling machinery.
• Electronics Assembly: Safety guarding for small-scale presses or automated assembly benches.
• Automated Warehousing: Utilizing the Muting function to allow pallets to pass through the light curtain while keeping the “stop” signal active if a human attempts to walk through.
