• Protection Level: Usually IP65, providing good dust and water resistance to adapt to harsh industrial environments.

• Operating Temperature: The operating temperature range is generally -20℃ to +70℃, and the storage temperature is -40℃ to +85℃, with strong temperature adaptability.

• Safety Control of Chemical Reactors: In chemical production, the F3349 module can be used in the safety control system of reactors. It receives signals from sensors such as temperature, pressure, and liquid level through 16 digital input channels to monitor the operating status of the reactor in real-time. When abnormal conditions such as excessive temperature or overpressure occur, it drives actuators like emergency shut-off valves and cooling system valves through 8 digital output channels to quickly take safety measures and prevent accidents.

• Emergency Shutdown Control of Oil and Gas Pipelines: In oil and gas transmission pipeline systems, the F3349 module can be connected to leakage detection sensors, flame detectors, and other devices along the pipeline to receive their switching signal inputs. When dangerous situations such as pipeline leakage or fire are detected, the module controls emergency shutdown devices through output channels according to preset logic, closes pipeline valves, cuts off oil and gas transmission, ensures pipeline safety, and realizes the safety interlock function.

• Equipment Protection in Power Plants: In power plants, the F3349 module can be used in the protection systems of key equipment such as generators and transformers. It receives digital signal inputs from overvoltage and overcurrent protection devices. When abnormalities occur in the equipment, it promptly drives emergency isolation devices of generators, valves of transformer cooling systems, etc., through output channels, enabling the equipment to quickly enter a safe state and avoiding equipment damage and large-scale power outage accidents.

• Safety Gate Control in Automobile Production Lines: In automobile manufacturing production lines, the F3349 module can be connected to safety gate sensors to receive signals of the safety gate's open/close status. When the safety gate is not closed or is abnormally opened during production, the module controls the shutdown of relevant equipment on the production line through output channels to prevent harm to operators and ensure safe and orderly production.

• Pump Start/Stop Control in Sewage Treatment Plants: In sewage treatment plants, the F3349 module can real-time monitor signal inputs from water quality sensors and liquid level sensors to keep track of sewage quality and liquid level. When the water quality exceeds the standard or the liquid level reaches the set threshold, the module controls the start and stop of pumps through output channels to ensure the normal operation of the sewage treatment process and avoid problems such as sewage overflow or substandard treatment.
