X3: Digital outputs - general purpose DO0 - DO3
The general purpose digital outputs are optically isolated. They source current from
the user supply as shown below. The maximum saturated voltage across the outputs
when active is 1.0 V DC, so it can be used as a TTL compatible output.
The output includes a self-resetting fuse that operates at approximately 200 mA. The
fuse can take up to 20 seconds to reset after the load has been removed. If the output
is used to directly drive a relay or any other inductive load, a suitably rated diode must
be fitted across the load, observing the correct polarity. This is to protect the output
from the back-EMF generated by the load when it is de-energized.
When the MicroFlex e190 is connected to Mint WorkBench, the active level of the
output can be configured using the Digital I/O tool. Alternatively, the Mint keyword
OUTPUTACTIVELEVEL
can be used in the command window. Other Mint keywords
such as
COMPAREOUTPUT
,
GLOBALERROROUTPUT
,
DRIVEENABLEOUTPUT
and
MOTORBRAKEOUTPUT
can be used to configure the output. The state of the digital
outputs can be viewed using the Mint WorkBench Spy window Axis tab.
Note:
By default DO0 is configured as a global error output. Use the Digital I/O tool or
the Mint command
GLOBALERROROUTPUT = -1
to release the output for other
purposes. See the Mint help file for details.
