5.3.7 Digital outputs 8-11 (NES002-501 / NES002-502 only)
Digital outputs DOUT8 - DOUT11 on the backplane are not buffered by the
opto-isolator card; they are connected directly to the NextMove ES outputs.
CAUTION
When an output is activated, it is grounded through the ULN2003, which can sink up to 50 mA
per output (all outputs on, 100% duty cycle). If an output is used to 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.
