SIL2 HART® Isolating Driver 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. TECHNICAL DATA Supply 24 Vdc nom (18 to 30 Vdc), reverse polarity protected. Current consumption: 70 mA (D5020D), 35 mA (D5020S), @ 24 Vdc with 20 mA output on 500 Ω load, typical. Power dissipation: 1.3 W (D5020D), 0.65 W (D5020S), @ 24 Vdc with 20 mA output on 500 Ω load, typical. SIL 2 / SC 3 Output to Zone 0/Div. 1 Installation in Zone 2/Div. 2 2 fully independent channels 4-20 mA Input, Output Signal 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 Input 4 to 20 mA with ≤ 2.5 V voltage drop, reverse polarity protected in normal operation, ≥ 5 kΩ impedance (≈ 2 mA sinking from 10 to 30 Vdc) when fault condition detected. Output 4 to 20 mA, on max. 700 Ω load. Response time: 25 ms (0 to 100 % step change). Fault Field device and wiring open circuit or short circuit detection; short circuit detection can be disabled via dip-switch. Short output: load resistance < 50 Ω or < 100 Ω dip-switch selectable (≈ 2 mA forcing to detect fault). Open output: load resistance > (21 V / Loop current) -300 Ω (for example, if Loop current = 20 mA: load resistance > (21 V / 20 mA) -300 Ω = 750 Ω). Fault signaling: voltage free NE SPST optocoupled open-collector transistor (output de-energized in fault condition). Open-collector/drain rating: 100 mA @ 35 Vdc (≤ 1.5 V voltage drop). Leakage current: ≤ 50 µA @ 35 Vdc. Response time: ≤ 30 ms. FUNCTION DIAGRAM Additional installation diagrams may be found in Instruction Manual.
