Description
Description
trodeks's DMD4008 accepts aresistance input from potentiometer,slidewire, linear position,displacement, or rotational devicesand provides an optically isolatedDC voltage or current output that islinearly related to the potentiometerposition. It will accept anypotentiometer with a value of 0 to100 ohms through 0 to 1 Megohmswithout recalibration and withoutaffecting accuracy. The DMD4008output can be field configured viaexternal rotary and slide switches,Offsets and/or input ranges otherthan 0 to 100% of the potentiometerrange can also be selected.
