Introductions:
QB3000N is designed interchangeable modularization and consists of
cast-aluminum shell, sensor breathing device of stainless, sensor
module, display module, the main control module, digital
communicating module, dust proof hood and calibrating cap. Each
module can be replaced by the other module while the performance
remains.
The original gas detector is mainly made up of the main control
module and intelligent sensor module. The relay output and the
acousto-optic alarm output are optional. RS485 communicating module
is for isolated RS485 signal output, LCD or LED module is inserted
to get the digital display, low and high alarm, failure indication
and the infrared remote control.
The alarm set-points, calibration value, the baud rate and IP of
the original gas detector can be adjusted.
The detector has isolated RS485 output and standard Mod bus-RTU
communicating protocol, can be connected with Siemens PLC or other
PLC in the nation or abroad directly, having no need to add more
RS485 isolated module.
LCD display module and LED display module can be interchanged,
supporting swift hot swap, support plug and play functionality.
The sensor module and the connection interface in the detector have
jack and plug prevent improper insertion. Just spin and press the
plug gently, the plug can be inserted the jack.
The sensor module of the detector can be replaced by the same type
module and the different gas sensor module, and different range
sensor module. The detector can distinguish and operation
itself.
Whatever the sensor module is chosen to replace the original one,
there is no need to re-calibrate it. The detector automatically
distinguishes the sensor module, reads the ex-factory calibration
value and the related setting value and operates detecting when the
self-inspection is done. When the ex-factory new sensor module is
inserted the original detector, the detector will have the same
detecting, alarm accuracy as the new detectors.
When the sensor out of service or the sensor fails, the user can
check and solve the problem by replacing spare modules, saving the
time and cost.
