Analog signal conditioner D5020S

4-20 mAisolatedDIN 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.SIL 2 / SC 3Output to Zone 0/Div. 1Installation in Zone 2/Div. 24-20 mA Input, Output SignalHART® compatibleLine & Load short/open circuit detectionField fault mirroring to the PLC AOIn-field programmability by DIP SwitchHigh AccuracyThree port isolation, Input/Output/SupplyTechnical Specifications:Supply: Voltage: 24 Vdc nom (18 to 30 Vdc), reverse polarity protected. Current Consumption: 35 mA @ 24 Vdc with 20 mA output on 500 Ω load, typical. Power Dissipation: 0.65 W @ 24 Vdc with 20 mA output on 500 Ω load, typical.Input: Type: 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: Type: 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 (e.g., 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).
