Page 2: Technical Data
Characteristics General Description: The single and dual channel DIN Rail Isolating Driver, D1020S and D1020D, isolates and transfers a 4-20, 0-20 mA signal from a controller located in Safe Area to a load of up to 750 Ω in Hazardous Area. It has a high output capacity of 15 V at 20 mA combined with a low drop across its input terminals. The circuit allows bi-directional communication signals, for Smart I/P. -

In fact, the analysis results got for D1020S (single channel) are also valid for each channel of D1020D (double channel).

Page 8: Operation
The wiring cables have to be proportionate in base to the current and the length of the cable. On the section “Function Diagram” and enclosure side a block diagram identifies all connections. Identify the number of channels of the specific card (e.g. D1020S is a single channel model and D1020D is a dual channel model), the function and location of each connection terminal using the wiring diagram on the corresponding section, as an example: Connect 24 Vdc power supply positive at terminal “3”... - Page 9 DC supply 30 V range at terminals 1 (+) and 2 (-), the multimeter (DMM) for the reading in DC supply 20 mA range at terminals 14 (+) and 15 (-). Execute the next test to verify D1020S unit channel or execute it twice to verified both D1020D unit channels. ...
