QNN1 Type Twin DC Neutral Q-Series Line Relay

The QNN1 Relay is a DC neutral, tractive armature, line relay designed for railway signaling and automation applications. It comprises two electrically independent relays mounted on a single base, making it functionally equivalent to two QN1 relays. This relay is engineered to operate at 12V, 24V, and 50V DC, offering high reliability in railway environments. It is widely used in railway interlocking, track circuit monitoring, and fail-safe operations. The QNN1 relay adheres to BR 930 Series standards, ensuring robust performance. Its compact structure and 8-pair contact limitation make it suitable for diverse railway applications.
