YCLH Sensor
1 / 4
Air Pressure + temperature + humidity: Primarily used in environments with high cleanliness requirements, such as operating rooms, clean workshops, cleanrooms, and laboratories.
2-channel digital input (DI): Accepts dry contact signals for monitoring device status.
1-channel RS485 to Ethernet: Acts as a protocol conversion gateway for Modbus RTU devices.
1-channel relay output (DO): NO/NC contacts for intelligent control of fans, alarms, or lights.
Ethernet Communication: Supports MQTT, SNMP, Modbus TCP, and UDP protocols.
PoE Power (802.3af): Simplifies installation via Ethernet cable power supply, with DC backup reserved.
Local Data Logging: Built-in memory for 100,000 records for historical tracing.
Multiple Alarm Mechanisms: High/low thresholds with email, SNMP traps, and local sound/light indicators.
Wide Range Design: Operates from -20 °C to 65 °C.
Rugged Housing: Metal or flame-retardant plastic housing for superior durability and shielding.
