The Signal Isolators convert a standard control to an isolated input. By using external resistors, the input signal can be changed to
0-100VDC, 0-200VDC and 4-20mA. The output voltage is 0-10VDC which can be rescaled with the built-in MIN and MAX trimpots.
Selectable AC line jumpers allow the SI-5 to be used either with 115 or 208/230 Volts AC controls. Installation is made by simply
mating the unit to the speed control with the built-in quick-connect terminals.

Models where used: KBMM, SI-6 (9444).
