3Product description
The gas detection control panel is suitable for applications that place increased demands on the complexity of the system. Up
to 100/200 transmitters of toxic and explosive gases can be connected to the control panel using 8 independent digital buses
(BUS). If higher system reliability is required, these buses can be combined and connected in a ring topology (LOOP).
The control panel has 20 output programmable relays. Each of these relays can be freely selected to 4 levels of detection, PEL
and fault from each transmitter.
The control panel has an integrated DIN rail inside the box with the possibility of adding other components such as relays,
auxiliary sources, etc.
If analog transmitters are required, they can be connected via a 4-20mA analog input card with HART support and a card with
output relays.
The control panel has an optional LTE modem with connection to the DegaCloud service for remote management and
visualization via the internet.
The graphic display allows clear visualization of the detection status, viewing the alarm history, and also the complete settings
of the control panel without the need to use a PC.
