Typical Application 

 
UIM240xx controller’s wiring is very straightforward as shown in following Figure. 
Terminal 6 (SHDN) can be left open if offline is not needed.   

 

 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Optically Isolated Input Interface 

 
UIM240xx controllers’ logic control inputs are all optically isolated. All opto-couplers 
share one common anode (Vcc) as shown in above schematic diagram.  Typically, Vcc is 
5V. However, 3.3V or voltages higher than 5V are also acceptable, so long as the current 
through the opto-coupler’s emitter is between 5~20mA.  
 
Should a voltage higher than 5V be applied to Vcc, an additional resistor is needed for 
every terminal to ensure that the current through each emitter does not exceed 20mA.
