In general, most 3-wire transducer systems requiring +25V or -25V at no more
than 25 mA can be accommodated by connecting like.
3-wire sensors are wired identically to eddy current probes (power polarity is
set in module configuration). See

2-wire Self-generating Velocity Sensors

If self-generating, no transducer power connection is required. A list of
appropriate terminals for each channel follows.
