Mounting and Connection to Data Acquisition Boards
The SC-2062 has metal standoffs so the board can sit on a workbench near the host computer.
You can use an optional rack-mount chassis, which can be fitted with a flat acrylic plastic cover.
The SC-2062 grounds to its metal standoffs, and thus to the rack, when it is mounted in the
chassis.
Warning:
The SC-2062 must be completely enclosed if any onboard voltages or any voltages
connected to the relays can exceed 30 V.
