5 DGND Digital ground a3
4 DOUT11 Digital output DOUT11 c22
3 DOUT10 Digital output DOUT10 c16

1 DOUT8 Digital output DOUT8 a13
CAUTION: Digital outputs DOUT8 - DOUT11 on the backplane are not buffered by
the opto-isolator card; they are connected directly to the NextMove ES
outputs.
When an output is activated, it is grounded through the ULN2003, which can sink up to 50mA
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.
