๐ก Key Summary: 1-Channel Leak Detection Control Module for Solvent & Oil Sensors
YHSM-01S-A is a 1-channel leak detection control module that receives signals from solvent and oil leak detection sensors and immediately activates on-site alarms and equipment interlocks. With an LCD display, you can check operating status and adjust sensitivity directly in the field, making it ideal for both retrofit maintenance and new installations. It is designed for broad compatibility, especially with 2-wire leak detection sensors, enabling flexible system configuration across diverse site conditions.
YHSM-01S-A: The Core Control Module for Solvent & Oil Leak Detection Systems
On-site Setup, Alarm Outputs, and Monitoring Integration in One Unit
Solvent and oil leaks can lead to fire/explosion risks, production downtime, and environmental contamination. Thatโs why early detection and immediate equipment interlocking are essential. YHSM-01S-A processes sensor signals reliably and quickly delivers outputs to external devices such as beacon lights, buzzers, and PLCs. It also supports monitoring integration via RS-485 (Modbus), improving both on-site response and overall operational efficiency.
โก Fast Decision & Immediate Alarm Output
โข Reliably processes leak signals from sensors and outputs instant alarms (Relay & LED).
โข Shortens initial response time to minimize leak spread and secondary damage.
๐ Flexible Sensor Compatibility & System Scalability
โข A 1-channel control module built for solvent & oil detection sensors, enabling systems tailored to site requirements.
โข Designed to work broadly with 2-wire leak detection sensors, expanding options for maintenance and replacement.
๐ฅ๏ธ LCD-Based On-Site Setup & Status Monitoring
โข Check operating status and settings directly on-site via LCD (25ร15mm).
โข Adjust sensitivity on the module without additional equipment.
โ๏ธ Built-in Outputs & Communication for Equipment Integration
โข Provides 3 NO contacts and 1 NC contact for easy connection to beacon lights, buzzers, and PLCs.
โข Supports RS-485 communication and Modbus protocol for integration with central monitoring systems.
