12. Description of Equipment:
General - The intrinsically safe indicator type CAIXS2-.... Is used for date handling and indication in a weighing
system. Intrinsically safe analog weighing platforms or load cells can be connected to the internal analog digital
converter board, which can be replaced by a RS232/RS485 data output board for connection to intrinsically safe
digital weighing platforms or scales. Additional data transfer can be done by an intrinsically safe RS232, RS485 or
RS422 data output board with and without digital I/O signals.
Construction - The housing of the display unit consists of stainless steel with a membrane switch glued to the
Front panel. The weighing modules housing consists of painted aluminium and/or stainless steel.
Ratings - The ambient temperature range of the CAIXS2-.... Intrinsically Safe Indicator, which is also listed on
controlled drawing 66015-751-07, is -10°C to +40°C.
