4-20 mA analog signal transmitter D1020S

0-20 mA

1 CH, 0/4-20 MA I/P ISOLATING DRIVER, SIL 2 DESCRIPTION The single channel DIN-Rail Isolating Driver, D1020S, 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 the 4-20 mA input range, a field open circuit reflects a high impedance to the control device output circuit. FEATURES • Output to Zone 0 (Zone 20), Division 1, installation in Zone 2, Division 2. • 4-20 or 0-20 mA Input, Output Signal. • Wide Band Smart Communication, Hart compatible. • Field open circuit detection. • High Accuracy. • Three port isolation, Input/Output/Supply. • High Reliability, SMD components. • High Density, two channels per unit. • Simplified installation using standard DIN Rail and plug-in terminal blocks. • 250 Vrms (Um) max. voltage allowed to the instruments associated with the barrier.
