💡 Key Summary: 1-Channel Leak Detection Control Module for Acid/Alkali & Inorganic Solution Sensors
YHSM-01S-AR is a 1-channel leak detection control module that receives signals from acid/alkali and inorganic solution leak detection sensors and provides alarm outputs and equipment interlocks directly on site. With the built-in LCD, operators can check operating status and adjust sensitivity in the field. This makes it ideal for applications that require strict management of corrosive chemicals such as chemical plants, semiconductor lines, and chemical handling facilities. It is designed for broad compatibility in 2-wire leak detection sensor environments, enabling flexible configurations for both retrofits and new installations.
YHSM-01S-AR: Field-Ready Control Module for Acid/Alkali & Inorganic Solution Leak Response
Alarm Output, Equipment Interlock & Monitoring Communication in One
Leaks of highly corrosive acids, alkalis, and inorganic solutions can lead to equipment corrosion, production shutdowns, and safety incidents. That’s why early detection and immediate response are critical. YHSM-01S-AR 1-Channel Leak Detection Control Module reliably processes sensor input signals to drive alarms to beacons/buzzers/PLCs, and supports monitoring system integration via RS-485 (Modbus), improving both on-site response and operational efficiency.
⚡ Fast Alarm Output & On-Site Response
• Processes sensor input signals and outputs instant alarms (Relay & LED).
• Helps shorten initial response time before leak spread and equipment damage progress.
🔗 Flexible Sensor Compatibility & Maintenance Efficiency
• 1-channel control architecture for acid/alkali & inorganic solution sensors, enabling site-optimized system design.
• Designed for broad compatibility in 2-wire leak detection sensor environments, expanding options for maintenance and replacement.
🖥️ LCD-Based Configuration & Status Monitoring
• Check operating status and settings on-site via LCD (25×15mm).
• Adjust sensitivity directly on the module to match site conditions.
⚙️ Built-in Outputs & Communication for Equipment Integration
• Provides 3 NO contacts and 1 NC contact for easy connection to beacons, buzzers, and PLCs.
• Supports RS-485 communication and Modbus protocol for integration with central monitoring systems.
