A number of connectors are located internally on the iSIC enclosure:
▫ Expansion Plugs – A number of connectors are located internally on the iSIC
enclosure. These allow an interface to the multitude of sensors in your system. An
iSIC data logger allows 4 RS-232 devices, RS-485 devices, 8 analog inputs, a tipping
bucket rain gauge, and 10 SDI-12 sensors to be connected at a single time. These
numbers can be further increased with expansions. See the following pages for more
information.
▫ Internal Battery – The NexSens iSIC comes standard with a sealed rechargeable lead
acid 12V 8.5 A-hr battery. Recharging is possible through the use of a float charger
or solar panel equipment.
▫ Fuses – Two fuses are located on the left edge of the plate inside the iSIC enclosure.
The top fuse connects to the internal battery. The bottom fuse connects to the
charger/external power. These are 3A time delay speed type fuses, rated for
250VAC.
