Industrial Intelligent Online Gas Monitor Controller 4-20mA Rs485 Modbus Multi Channels Gas Monitor System
YA-K300 series gas alarm controllers are designed to work in conjunction with our YA-D series gas detectors to create industrial gas control systems. This product is designed specifically for industrial environments and provides gas detection and early warning systems. The 4.3-inch industrial LCD display provides clear gas concentration measurements. When the concentration of gas exceeds a certain level, both audible and visual alarms are triggered. The product comes equipped with output relays that can drive the exhaust fan, solenoid valve, and other equipment in active and passive ways, making it highly adaptable to different field conditions.
The design of the YA-K300 series gas alarm controller meets national standards and provides fast response times, high reliability, low failure rates, and easy maintenance. In particular, the use of multiple event delay confirmation methods helps to prevent false alarms and ensures people's safety. The wall-mounted installation of the product allows for data upload from the gas detector to the controller's single-chip microcomputer for data processing, data display, output control, and other functions.
The YA-K300 gas alarm controller host is embedded with a microprocessor that has a variety of rich software functions. The controller is equipped with complete detector signal sampling, data real-time calculation, and system fault detection, among other functions.
An intelligent system supports %LEL, PPM, mg/m³, ug/m³, %VOL, and other units. With 2 sets of common relays and 8 sets of programmable relays, the controller has passive outputs that allow for easy connection to various external devices.
Two communication modes are supported, 4-20mA, and 485 bus. The YA-K300 series gas alarm controller is easy to install, and it offers real-time monitoring of the measured gas concentration within the detection area.
When the gas concentration reaches or exceeds the set alarm value, the controller will issue sound, light, and voice broadcast alarm signal. In addition, there is a monitoring system failure and fault acoustic and optical alarm function, which provides you with added safety and peace of mind.
The controller can trigger external devices when the preset logic relationship is satisfied, and external devices can be started through the controller. The storage capacity of the unit is impressive, with more than 2000 data records that can be stored safely.
