Power Input 90-264VAC 50/60 HZ

FDC-8100 1/8 DIN 

Future Design’s "100" series redefines the standard for 1/16, 1/8 and 1/4 DIN temperature controllers. Fast input scan rates ( 5 per second ), 18 bit input resolution and 15 bit output resolution as well as fuzzy modified PID control provide not only the highest accuracy, but temperature control minimizing over/under shoot while maintaining fast process response.
