BXI32 Gas control unit for parking and industrial plants, with ADDRESSED sensors BUS 485
Cod. BXI32 - Gas control unit for parking and industrial plants, with ADDRESSED sensors BUS 485
The experience and the knowledge acquired over the years within industrial sector and market together with the prestige that has always made BEINAT S.r.l. have allowed the design of a new Gas Control Unit the... “BXI32” which has the prerogative to control, through the connected addressed sensors to it from 1 to 32, the presence of gas: Toxic, Explosive, and Oxygen ecc.
The control unit BXI32 has been designed and built to meet the current requirements of the Market and in compliance with European Standard for checking gas presence in a versatile and innovative with addressed sensors through an addressed network RS-485 MODBUS.
The gas concentration that each sensor detects at rotation is read directly on the display that specifies the origin. When one of the connected sensors exceeds the pre-alarm setpoint, the control unit emits a proportional sound signal, based on the amount of gas detected, and shows on the display the number of the sensor, the amount of gas detected and its origin; the alarm triggered is saved in a memory (Datalogger). Should it be necessary, the data stored can be printed (up to maximum 50 events).
The control unit features two levels of hazard:
I LEVEL, pre-alarm. This data is variable. The technician can modify pre-alarm intervention for every sensor according to the type of plant to be controlled. The level can be selected from 3% to 16% of L.E.L. or from 45 to 240 ppm.
II LEVEL, general alarm. It is set to 20 % of L.E.L. or 300ppm
The control unit is equipped with 1 general alarm relay with/without Positive Safety to enable further independent control of two solenoid valves.. Up to 2 relay expansion cards CARD-RLS4 can be inserted if nedessary.
