SPINX1 5
OPERATION
ISOLATED OUTPUTS
TheSPINX1 provides 3 isolated outputs for use for spindle direction control, spindle
enable or other applications. These outputs are OPTO coupler Darlington transistors. They
are all isolated from one another so can be used for pull up or pull-down individually. They
will switch a maximum of 50 mA at 0 to 100 VDC. The ENABLE output is special as it uses
the same signal that enables the analog output. When the analog output is enabled, the
ENABLE OPTO output is on. The CW and CCW outputs can only be enabled then the
ENABLE input is asserted.

Note that the isolated outputs are all individual switches so must always have both
the + and - pins connected with switch polarity observed.
