ABB 2TLA010070R0000 Shunt trip unit

Description

ABB 2TLA010070R0000 Shunt trip unit

The Sentry USR10 is a highly flexible and universal safety relay designed to monitor a wide range of safety devices and implement various safety functions, achieving the highest safety levels in machinery.

• Product Name: Sentry USR10 Safety Relay

• Function: Universal safety monitoring device with advanced timer functions. It supervises signals from safety components and reliably isolates power to a machine’s hazardous movement when a safety function is triggered.

• Design: Compact, DIN rail mountable, with screw terminals for robust and reliable wiring.

• Display: Features a front display for configuration, troubleshooting, viewing error codes, and checking the error log.

⚙️ Technical Specifications (Product Parameters)

The key parameters define the relay’s capabilities and operational limits:

✨ Product Advantages (Product Advantages)

• Universal Monitoring: It can monitor virtually all common safety devices, reducing the need for multiple, specialized relays.

• Integrated Safety Timer: The accurate and configurable timer function ($0 \text{ to } 999 \text{ s}$) allows for advanced safety applications like OFF-delay, ON-delay, Time Bypass, and Time Reset, which are often required for controlled machine stops.

• Diagnostic Display: The built-in display provides clear and immediate status feedback, error codes, and troubleshooting information, significantly simplifying commissioning and maintenance.

• High Safety Level: Achieves the highest safety standards (PLe/Category 4/SIL3), suitable for use in high-risk industrial environments.

• Powerful Outputs: High output current capacity (up to $8 \text{ A}$ for NO contacts) can sometimes eliminate the need for an intermediate contactor, saving space and cost.

• Multi-Reset Capability: Supports Multi-reset, allowing up to 10 safety relays to be connected to a single reset button.

⚠️ Cautions (Important Notes)

1. Safety Circuit Design: The entire safety system design (including device placement, wiring, and functional logic) must adhere strictly to local and international machine safety standards (e.g., EN ISO 13849, EN 62061, NFPA 79). The relay only functions as one part of a certified system.

2. Configuration: The USR10 is highly configurable (via the front display). A custom configuration can and should be password-protected to prevent unauthorized changes that could compromise safety.

3. Wiring: Use the specified wire sizes and torque for the screw terminals to ensure a secure, vibration-resistant, and high-integrity connection.

4. Power Supply: Only use a suitable $24 \text{ VDC}$ isolating power source and ensure proper fusing in accordance with safety standards.

🏭 Product Applications (Product Applications)

The ABB Sentry USR10 (2TLA010070R0000) is ideal for demanding machine safety applications, including:

• Emergency Stop (E-Stop) Monitoring: Monitoring single or dual-channel E-Stop buttons.

• Safety Gates/Interlock Switches: Supervising mechanical and non-contact gate switches to ensure machine shutdown when access points are opened.

• Opto-electronic Safety Devices: Monitoring OSSD (Output Signal Switching Device) outputs from safety light curtains, safety laser scanners, and safety light beams.

• Pressure-Sensitive Devices: Integration with safety mats, safety edges, and safety bumpers.

• Two-Hand Control Devices: Monitoring two-hand control stations for punch presses and similar machines.

• Delayed Shutdowns: Implementing controlled, delayed stops for machinery (e.g., allowing a motor to coast down before allowing access) using the time-delayed outputs.
