WARNING
The Digital I/O port of the Model 2601/2602 SourceMeter is not
suitable for control of safety circuits and should not be used to
control a safety interlock. The Model 2611/2612 SourceMeter
Digital I/O port includes an Interlock line to be used as safety
interlock. When an interlock is required for safety, a separate
circuit should be provided that meets the requirements of the
application to reliably protect the operator from exposed
voltages.
Digital I/O configuration
shows the basic configuration of the Digital I/O port. Writing a 1 to a
line sets that line high (~ +5V). Writing a 0 to a line sets that line low (~0V). Note
that an external device pulls an I/O line low by shorting it to ground, so that a
device must be able to sink at least 480
μ
A per I/O line.
