5.2.5 General purpose / status output DOUT0

1	11	Location	Connector X3, pins 1 & 11
			(Mating connector: Weidmüller Minimate B2L 3.5/20)
		Name	Status / DOUT0
		Description	General purpose opto-isolated digital output
			Output current:	100mA maximum
			User supply	+28VDC maximum
			Update interval:	1ms

The optically isolated general purpose / status output is designed to source current from the user supply as shown in Figure 30. 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.

By default, DOUT0 is configured as an error status output, which becomes inactive in the event of an error. When the MicroFlex e100 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.
