AUXILIARY POWER OUTPUTS
FLX modules each have two 18 V DC outputs, for I/O devices that require loop power.
For 3-wire connections return can be through any COM terminal, but it is recommended that Auxiliary power
wiring is through terminal 14, the COM between the two Auxiliary power terminals.
The DC output terminals provide a minimum of 18 V DC, but the combined load (on each IO module) must
remain below 60 mA.
