SLSC-12001 Chassis Block Diagram
The chassis power comes from an ex24 V supply and is distributed to each SLSC module
through an internal power bus. The +24 V bus has input overvoltage, reverse voltage, and short
circuit protection at each SLSC module output. The chassis does not have a power switch,
therefore power is energized as soon as the external power supply is connected to the chassis
and powered.
The SLSC-12001 chassis communicates with each module through the SLSC interface and
manages the Ethernet connectivity with a host computer.
The SLSC-12001 chassis also has built-in diagnosis functions, such as battery and fan
monitoring, that is accessible through the NI-SLSC driver. The chassis will shut down the
24 V rail supplied to the module unless all 5 fans are powered.
