YA-K300 Combustible CH4 C3h8 Methane Propane Gas Leak Detector Controller
The YA-K300 series gas alarm controllers are an ideal solution for constructing industrial gas control systems. Our controllers can be easily combined with our YA-D series gas detectors to create a reliable and effective gas detection and early warning system. Our product is specially designed to operate in industrial environments, and features a 4.3-inch industrial LCD display that clearly and effectively displays the concentration of gas to be measured.
Our product features audible and visual alarms that are activated when gas concentrations exceed safe levels. Additionally, our controllers are equipped with several output relays that drive exhaust fans and solenoid valves to offer versatile control options for various field conditions. Our controllers follow national standards and are renowned for their fast response times, high reliability, low failure rates, ease of maintenance, and other features that make them the preferred choice for industrial applications.
One of our most notable features is our multiple event delay confirmation system, which helps prevent false alarms. This feature offers a strong guarantee for the safety of people and property in industrial environments.
The YA-K300 gas alarm controller host is an advanced microprocessor with multiple software functions. It provides complete detector signal sampling, real-time data calculation, system fault detection, and power management. Additionally, the controller features key scanning, display driver, alarm display, alarm peripheral driver and many other functions to make it an intelligent system.
The system is capable of supporting various units of measurement such as %LEL, PPM, mg/m³, ug/m³, %VOL and more. It comes equipped with 2 sets of common relays and 8 sets of programmable relays with passive outputs, making it easy to connect the controller to external devices.
The YA-K300 gas alarm controller host is compatible with 4-20mA and 485 bus two communication modes. The controller offers easy installation, and the real-time monitoring of the measured gas concentration in the detection area ensures the safety of the environment.
When the gas concentration in the detection area reaches or exceeds the set alarm value, the controller automatically issues a sound/light/voice broadcast alarm signal. Additionally, the system features monitoring system failure and fault acoustic and optical alarm functions to keep you informed in the event of any issues.
The controller's external devices can be started through the controller with ease. The connected external device will act on its own when the preset logic relationship is satisfied. Furthermore, the controller can store more than 2000 data records for future reference.
