ABB UNS0119A-Z,V1
Product introduction
The ABB UNS0119A-Z, V1 is a high-integrity safety relay module designed for critical machine and process safety applications, part of ABB’s SafeLine series of safety automation components. This compact relay is engineered to monitor safety devices such as emergency stops, light curtains, and interlock switches, ensuring rapid shutdown of hazardous processes when risks are detected.
ABB UNS0119A-Z, V1 acts as a failsafe intermediary between safety sensors and machine control systems, verifying input signals through redundant channels to prevent false triggers or dangerous failures. Its SIL 3 certification makes it suitable for applications where human safety and equipment protection are paramount, including automotive manufacturing, packaging lines, and industrial robotics. Whether integrated into new installations or retrofitted into existing systems, ABB UNS0119A-Z, V1 provides reliable safety monitoring without compromising operational efficiency.
Core advantages and technical highlights
Advanced safety integrity: ABB UNS0119A-Z, V1 achieves SIL 3 and PLe ratings, the highest safety categories for industrial applications, ensuring it meets the strictest global safety standards. Its dual-channel design with cross-monitoring detects internal faults, automatically triggering a safe state to prevent hazardous conditions.
Flexible configuration: Unlike fixed-function safety relays, ABB UNS0119A-Z, V1 offers configurable input types (PNP/NPN) and reset modes (manual/automatic), adapting to diverse safety device requirements. This versatility eliminates the need for multiple relay models, simplifying inventory management and system design.
Ultra-fast response: With a response time of ≤10 ms, ABB UNS0119A-Z, V1 minimizes the time between hazard detection and machine shutdown, reducing the risk of injury or equipment damage. This rapid reaction is critical for high-speed machinery where even milliseconds matter.
Compact design: At just 17.5 mm wide, ABB UNS0119A-Z, V1 saves valuable panel space, allowing more safety functions to be integrated into limited enclosures. Its DIN rail mounting compatibility simplifies installation in standard control cabinets, reducing assembly time.
Typical application scenarios
In automotive assembly lines, ABB UNS0119A-Z, V1 monitors emergency stop buttons and robot cell interlocks, ensuring immediate shutdown if operators enter hazardous zones. Its dual-channel inputs provide redundant monitoring of light curtains around welding stations, preventing accidental exposure to arc flashes while allowing quick resumption of production after safety checks.
Within packaging machinery, ABB UNS0119A-Z, V1 safeguards operators from rotating blades and conveyor pinch points by monitoring guard door interlocks. Its configurable reset mode allows either manual reset (for high-risk areas) or automatic reset (for less critical sections), balancing safety with productivity. The relay’s fast response time is particularly valuable for high-speed bottling lines, where rapid stops prevent product jams from escalating into equipment damage.
In food processing plants, ABB UNS0119A-Z, V1 integrates with wash-down rated safety sensors, monitoring access to mixing tanks and slicing machines. Its wide operating temperature range ensures reliable performance in both cold storage areas and high-heat processing zones, maintaining safety even in harsh environmental conditions.

Installation, commissioning and maintenance instructions
Installation preparation: Before installing ABB UNS0119A-Z, V1, ensure the DIN rail is properly grounded and mounted in a clean, dry enclosure. Required tools include a small flat-head screwdriver for terminal connections and a multimeter for continuity checks. Use twisted-pair cables for safety inputs to minimize electromagnetic interference. Verify that the 24 V DC power supply is isolated from other circuits and protected by a 1A fuse. Label all connections clearly to avoid miswiring during commissioning.
Maintenance suggestions: For ABB UNS0119A-Z, V1, perform monthly functional tests by activating connected safety devices (e.g., pressing emergency stops) to verify proper shutdown operation. Inspect terminals quarterly for tightness and signs of corrosion, as loose connections can compromise safety performance. Document all test results and store them for compliance audits. If a fault is indicated by the relay’s LED status indicator, replace ABB UNS0119A-Z, V1 with a new unit (do not attempt repairs) and use ABB’s diagnostic guide to identify root causes. Always use genuine ABB replacement parts to maintain safety certifications.
