MN1943
5.3.7 General purpose digital output DOUT1
Location
Connector X3, pins 3 & 15
(Mating connector: Weidmüller Minimate B2L 3.5/24 LH)
Name
DOUT1
Description
General purpose opto-isolated digital output
Output current:
100 mA maximum
User supply:
28 VDC maximum
Update interval:
1 ms
The optically isolated general purpose output is designed to source current from the user supply
as shown in Figure 54. The TLP 127 has a maximum power dissipation of 150 mW at 25
°
C. The
maximum saturated voltage across the outputs when active is 1.0 VDC, 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 may
take up to 20 seconds to reset after the load has been removed. If the output is used to directly
drive a relay, a suitably rated diode must be fitted across the relay coil, observing the correct
polarity. This is to protect the output from the back-EMF generated by the relay coil when it is
de-energized. The sense of the output can be configured in Mint WorkBench, and its state is
displayed in the Spy window.

When the MotiFlex
e
100 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
(see section 3.7.6)
can also be used in the command window. The state of the digital output can be viewed using the
Mint WorkBench Spy window’s Axis tab. See the Mint help file for details.
