4-20 mA signal conditioner D5020D

high-densityDIN rail

The Isolating Driver D5020 module is a high integrity analog output interface suitable for applications requiring SIL 2 level in safety related systems for high risk industries. It isolates and transfers a 4- 20 mA signal from a controller located in Safe Area to a load in Hazardous Area. It has a high output capacity combined with a low drop across its input terminals. The circuit allows bi-directional communication signals, for HART® smart positioners. Line and load open/short circuit detection is provided: the fault in the field is directly mirrored to the PLC AO and it is also reported by opening the fault output. FEATURES Output to Zone 0/Div. 1 Installation in Zone 2/Div. 2 2 fully independent channels HART® compatible Line & Load short/open circuit detection Field fault mirroring to the PLC AO In-field programmability by DIP Switch High Accuracy Three port isolation, Input/Output/Supply High Density, two channels per unit
