Screw Terminal Connections for the SC-2072
The SC-2072 board connects all fifty I/O signals from the DAQ device to screw terminals on board.
Additionally, twelve undedicated screw terminals are located adjacent to the general-purpose
breadboarding area.
Warning:
Connections, including power signals to ground and vice versa, that exceed any of the
maximum input or output voltage ratings on the SC-207X Series boards can result in
damage to any or all of the boards connected to the SC-207X Series boards, to the host
computer, and to the SC-207X Series boards. Overvoltage conditions also can present a
shock hazard to you. National Instruments is
NOT
liable for any damages or injuries
resulting from incorrect signal connections.
Rack-Mount Chassis Cover Attachment
The optional 19-in. rack-mount accessory includes a flat, acrylic plastic cover that can be installed
using the four screws included in the kit. Covering the top and bottom is required for safety reasons if
an SC-206X Series board in the same enclosure is to be used in high-voltage situations (see the
following warning). Remember that voltages above the 42 V peak cannot be applied to the SC-207X
Series inputs.
Warning:
The SC-206X Series boards must be completely enclosed if any onboard voltages or any
voltages connected to the relays can exceed 42 V.
