Selectable spike and low pass filters 

CW/CCW open collectors (opto-isolators) for use as discrete control inputs to the inverter 
for motor operation.  

If input signal exceeds configured input range.  Selectable and adjustable. 

0 to 20 mA, 4 to 20 mA 

0 to 5 Vdc, 1 to 5 Vdc with 250 ohm resistor; (0 to 16 Vdc with 800 ohm resistor) 

Provides output voltage ratiometric to shaft position and potentiometric to supply voltage 
(1 to 20 Vdc) without a slidewire. Emulates a 100 ohm to 1000 ohm slidewire. 10 mA 
output maximum. 

Input signal, output signal and power are isolated from each other.
