ABB has introduced a new tension electronic component in automation control, the SPAJ140C, an innovative product that provides more efficient and accurate tension control capabilities for industrial automation control systems.
​The SPAJ140C tension electronics is a high-performance product designed by ABB for the tension control needs of industrial automation. It has a wide range of functions and technical features for a variety of industrial automation applications, including but not limited to radiant feeders in direct, resistance or impedance grounded power systems as selective short-circuit and ground fault protection. The SPAJ140C is a combined overcurrent and ground fault relay with a highly flexible trip and signaling device.
​The main features of the tension electronics include:
​Versatility: The SPAJ140C not only provides overcurrent protection, but also ground fault protection to meet a variety of protection needs.
Flexibility: Single-phase, two-phase or three-phase overcurrent protection and directional ground fault protection can be used according to the requirements of use.
Reliability: Designed for stable operation in harsh industrial environments with high reliability and stability.
Easy maintenance: With self-checking and adaptive relay protection, maintenance and troubleshooting are simplified.
Advanced technology: Automatic patch packaging process, with strong anti-interference ability, to ensure accurate measurement and counting.
SPAJ140C tension electronic components are widely used in steel, paper, chemical, textile and other industries to provide accurate tension control for material handling, winding, unwinding and other processes to improve production quality and efficiency. The SPAJ140C combined overcurrent and ground fault relay is designed for radiant feeders in direct, resistance or impedance grounded power systems as selective short-circuit and ground fault protection.
