RP56LD-6785-19 on stock The DTL23A has a high impedance isolated analog input, that allows the analog inputs to be connected directly across the load. The DTL23A sinks 2.0 amps for a 10V full scale input or I = 0.2 x VIN. If you make VIN = VUOAD (the voltage across the load), then R = VLOAD/I = VLOAD / (0.2 x VLOAD) = 5 Ohms. Consequently, the load looks like a 5 0hm resistor.
