Page 6: Slsc-12001 Chassis Block Diagram
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. -
Page 7: Slsc-12001 Chassis Rear Transition Interface
SLSC-12001 Chassis Rear Transition Interface An optional secondary backplane, RTI, may be used with the SLSC-12001 chassis to route conditioned I/O signals directly to the DAQ system. The RTI can be used to distribute additional power to one or more modules as shown in Figure 4. -

Page 10: Removing Slsc Modules
Module Injector/Ejector Handle Removing SLSC Modules The SLSC-12001 chassis and the SLSC modules do not support hot Caution plug-in. The entire chassis must be powered down when a module is removed. Complete the following steps to remove an SLSC module from the chassis: Power off the main DC power source or disconnect it from the chassis before removing the module. -
Page 11: Connecting The Chassis
Connect the grounding electrode system of the facility to the chassis using the chassis grounding screw located on the back of the SLSC-12001 chassis. Refer to Figure 2 for the location of the chassis ground screw. Use an AWG 8 wire with a lug as appropriate for your application. -
Page 12: Powering On The Chassis
The SLSC-12001 chassis can draw a significant current from the +24 V power input to support module requirements. Refer to the Physical Characteristics section for wire gauge sizes permitted by the SLSC-12001 chassis connector when wiring the power. Minimize the cable length between the power supply and SLSC-12001 chassis. -
