The smartblast® RB1675 series introduces LTE communication to Becker Mining Systems proven smartblast® range of blasting units. The RB1675 is available in LTE Cat-M or LTE Cat 1 variants.
The RB1675 Controller Unit is capable of commanding up to 64 Remotes that can be either electric or non-electric, in 8 Remote groups.
The historical event log keeps a record of information such as unit state, post-blast motion detect value, firing voltage level, battery level and the date and time the event was logged.
Each Remote unit has a sensor that measures the seismic motion that may be expected when a successful blast detonation has occurred. The Controller unit then reports that a post-fire motion was detected, useful in underground operations when the successful initiation of a blast cannot be easily determined.
The automatic disarming function ensures that the unit returns to a safe state in the event of a loss of communications after a time out period.
The Sequential Fire feature allows the user to space the firings of each Remote unit so that they do not fire at the same time. The Controller waits for confirmation that one Remote has fired before firing the next Remote. This feature is particularly useful when firing multiple blocks where a delay is needed between each block.
The LCD display provides information that is supplemental to the basic operation of the RB1675. The LCD is rated for -20 to 70°C (-4 to 158°F).
The RB1675 has increased firing capacity. A minimum of 350V, allowing for approximately 75 electric caps in series, or a maximum circuit resistance of 150Ω.
