Industrial Intelligent Online Gas Monitor Controller 4-20mA Rs485
Modbus Multi Channels Gas Monitor System
Product Description:
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.
Features:
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.
