ABB Tina 12A Safety Relay: Industrial Safety Guardian
Industrial Safety Cannot Be Compromised
On automated production lines, safety systems are the last line of defense protecting operator lives. The ABB Tina 12A safety relay is specifically designed for safety light curtains, emergency stop buttons, safety door switches, and other safety devices. Compliant with international safety standards, it provides reliable protection for your factory operations.

Key Safety Features
- Dual-channel redundant design: Two independent safety channels operate simultaneously — a single-channel fault does not compromise safety functionality.
- Cross-fault detection: Automatically detects short circuits or cross-talk between channels, ensuring safety integrity.
- Manual or automatic reset: Selectable reset mode meets different safety level requirements based on application risk assessment.
- LED status indication: Clear display of power supply, channel status, and output status for rapid diagnostics.
- Compact design: At only 22.5mm wide, it saves valuable control cabinet space.
Integration with ABB Safety Light Curtains
The Tina 12A pairs perfectly with ABB Orion series safety light curtains. The light curtain OSSD outputs connect directly to the Tina 12A input channels. When the light curtain is interrupted, the Tina 12A disconnects safety outputs within milliseconds, stopping hazardous motion. Total response time typically falls within 10-20ms — far exceeding international safety standard requirements.
Installation and Wiring Guidelines
- Verify safety level requirements: Conduct a risk assessment to determine the required PL (Performance Level) and select the appropriate reset mode.
- Use dedicated safety wiring: Separate safety circuit wiring from general control wiring to prevent electromagnetic interference.
- Test safety function after installation: Verify that all safety outputs disconnect when the safety device is triggered. Document test results.
- Periodic testing: Test the safety function monthly in high-risk environments. Replace relays showing intermittent behavior immediately.
Common Applications
- Press machine safety circuits with light curtain protection
- Robot cell safety door monitoring
- Emergency stop circuits for conveyor systems
- Safety mat and safety edge monitoring
- Two-hand control device monitoring
Frequently Asked Questions
What is the difference between PL e and SIL 3 safety ratings?
PL e (Performance Level e) is defined by ISO 13849-1 and represents the highest performance level for safety-related control systems. SIL 3 (Safety Integrity Level 3) is defined by IEC 62061 and represents a probability of dangerous failure of less than 10^-7 per hour. Both ratings indicate the highest level of safety reliability, and the Tina 12A meets both standards.
How often should safety relays be tested?
Safety standards recommend functional testing at least annually, with more frequent testing for high-risk applications. The Tina 12A includes a test input for automated function testing. Document all test results including date, tester, and test outcome. Replace any safety relay that fails functional testing immediately — do not attempt field repair.
Can one Tina 12A monitor multiple safety devices?
The Tina 12A has two input channels, suitable for monitoring one dual-channel safety device (such as a light curtain with OSSD outputs) or two single-channel devices connected in series. For systems with multiple safety devices, use multiple Tina 12A units or consider a safety PLC for more complex configurations.
