5-12 Input / Output MN1919
5.3.4 Status output - X3
Location Connector X3, pins 2 & 3
(Mating connector: W eidmüller Minimate B2L 3.5/14)
Name Status
Description Opto-isolated status output
Output current: 100mA maximum
User supply 30VDC maximum
Update interval: 500μs
The optically isolated status output is designed to source current from the user supply as
shown in Figure 36. The PS2562L has a maximum power dissipation of 200mW at 25°C. The
maximum saturated voltage across the outputs when active is 1.0VDC, so it can be used as a
TTL compatible output.
The output includes a self-resetting fuse that operates at approximately 200mA. 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 is connected to Mint WorkBench, the active level of the output can be
configured using the Operating Mode Wizard. Alternatively , the Mint keyword
OUTPUTACTIVELEVEL can be used in the command window . The output can also be
configured using the Mint keywords DRIVEENABLEOUTPUT or GLOBALERROROUTPUT.See
the Mint help file for details.
