Product Advantages and Features ABB SA168
- High contact reliability, long service life
ABB SA168 adopts silver alloy contact materials with excellent electrical conductivity and arc resistance, which can withstand frequent on-off operations under rated load conditions. Its contact electrical life exceeds 100,000 operations, which is 2 times longer than ordinary auxiliary relays, effectively reducing the frequency of component replacement and maintenance costs.
- Compact modular design, space-saving installation
The module features a slim DIN rail mounting structure, which can be seamlessly integrated into dense low-voltage control cabinets without occupying excessive space. Its pluggable terminal design enables quick wiring and disassembly, significantly shortening on-site installation and debugging time, and is especially suitable for retrofitting old control systems with limited cabinet space.
- Strong environmental adaptability, stable operation in harsh conditions
ABB SA168 is designed with wide-temperature adaptation and anti-electromagnetic interference capabilities. It can stably operate in harsh industrial environments with high humidity, dust, and strong electromagnetic interference, such as factory workshops and outdoor control stations. The module has no sensitive mechanical components, ensuring consistent performance even under vibration conditions.
- Flexible contact configuration, versatile application
ABB SA168 offers two contact configuration options (4× NO or 2× NO + 2× NC), which can be flexibly matched with different control circuit requirements. It can be used for signal isolation, load switching, and interlocking control, eliminating the need for multiple types of relays and simplifying the material management of automation projects.
Application Cases ABB SA168
- Industrial conveyor belt control system
In a food packaging workshop conveyor belt project, ABB SA168 is used to connect the PLC control signal and the contactor coil of the conveyor motor. The module isolates the low-power PLC output signal from the high-current contactor circuit, preventing electromagnetic interference from affecting the PLC’s normal operation. The reliable contact performance ensures the stable start-stop of the conveyor belt, reducing production line downtime by 15%.
- Building lighting and ventilation control
In a commercial office building intelligent control project, the module is integrated into the lighting and ventilation control circuit. It receives signals from the room temperature and light intensity sensors, and switches the lighting fixtures and ventilation fans on and off according to preset logic. Its compact design saves space in the building’s electrical distribution box, and the long contact life reduces the need for post-maintenance.
- Machine tool interlocking protection circuit
In a metal processing machine tool project, ABB SA168 is used in the safety interlocking circuit of the machine tool’s protective door and spindle motor. When the protective door is not closed properly, the module cuts off the spindle motor’s power supply, preventing safety accidents. The module’s anti-vibration performance ensures stable operation even when the machine tool is running at high speed.

Selection Suggestions
- For low-voltage control systems in industrial workshops, commercial buildings, and machine tool equipment, ABB SA168 is preferred due to its high contact reliability and flexible configuration options.
- If the project requires retrofitting old control cabinets with limited space, the module’s compact DIN rail design can effectively solve space constraints.
- For applications with frequent on-off operations, the module’s long contact electrical life provides a more cost-effective solution compared to ordinary auxiliary relays.
Precautions
- During installation, ensure that the coil voltage matches the control system’s output voltage to avoid coil burnout or failure to operate.
- When wiring the contact terminals, strictly distinguish between the control signal side and the load side, and avoid overloading the contacts beyond the rated current.
- Regularly check the connection tightness of the terminals to prevent poor contact caused by vibration or dust accumulation, which may affect the module’s normal operation.
- During maintenance, cut off the power supply first, and do not disassemble the module casing at will to avoid damaging the internal contact mechanism.
