๐ก Key Summary: Modular multi-channel leak alarm control system with flexible slot-based expansion
ย
YH-200L is a multi-channel leak alarm control receiver built with a modular card (slot) architecture. The system can be expanded by installing additional detection cards to match the required number of channels, making maintenance and replacement simple and efficient.
It integrates with a wide range of leak detection sensors according to site scale and equipment layout, making it an ideal unified control solution for multi-zone safety monitoring in large plants, semiconductor fabs, chemical facilities, and other industrial environments.
โ Excellent scalability: The card-type design allows easy channel (circuit) addition and changes, enabling flexible system expansion.
โ Unified monitoring: Integrates multiple leak detection channels into a single control receiver, saving space while enabling organized alarm management.
โ Optimized configuration: Sensor sensitivity and operating modes can be precisely adjusted based on target liquid characteristics and site conditions.
