5-12 Input / Output MN1942
5.2.6 General purpose output DOUT1
Location Connector X3, pins 3 & 13
(Mating connector: Weidmüller Minimate B2L 3.5/20)
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 34. The TLP127 has a maximum power dissipation of 150 mW at 25
° C.
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 MicroFlex
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. See the Mint help file for details.
