Wiring the Transistor Outputs
Both transistor outputs are of Sink (npn) type.
N
OTE
The outputs are not isolated.
Connect a current limiting device in series with outputs O0 and O1. These outputs
are not short-circuit protected.
Outputs O0 and O1 can independently be configured as either normal digital outputs or as
high speed PWM outputs.
Outputs O0 and O1 share the common point CM4.
CM4 is internally connected to the 0V point. To minimize EMI emission by high-speed
signals' wiring, do not externally connect CM4 to the system 0V.
Do not use point CM4 for any purpose other than connecting the digital output
load. Using it for any other purpose may damage the module.

Wiring the Analog Outputs
N
OTE
The outputs are not isolated.
Each output offers two modes: voltage or current. You can set each output
independently. The mode is determined both by wiring and by the hardware
configuration within the software application.
Voltage and current modes use distinct points. Connect only the point associated
with the selected mode; leave the other point unconnected.
Each output has its own common point (CM2 for O0, CM3 for O1). Connect each analog
output using its corresponding CM point.
CM2 and CM3 are internally connected to the 0V point. To minimize EMI pickup by analog
signals' wiring, do not externally connect CM2 or CM3 to the system 0V.
Do not use points CM2 or CM3 for any purpose other than connecting the analog
output load. Using them for any other purpose may damage the module.
