Product Introduction
The current‑sensing safety barrier isolates and converts signals from 2‑wire or 3‑wire transmitters or current sources in the hazardous area into a safe‑area output of 4–20 mA. This device requires an independent power supply and features three‑terminal isolation between input, output, and power. It includes built-in online fault self‑diagnosis and allows configuration—via PC or a handheld programmer—of signal types and the output behavior in the event of a signal fault.
Technical Specifications
- Power Supply: 18 VDC to 32 VDC, with reverse polarity protection.
- Operating power consumption: 1.3 W (24 V, single-channel full-load output); 1.8 W (24 V, dual-channel full-load output)
- Input signal: DC current signal
- Input impedance: ≤100 Ω
- Distribution voltage: Open-circuit voltage ≤ 26 V; at 20 mA, output voltage ≥ 16 V. Output signal: 4–20 mA.
- Allowable load: RL ≤ 550 Ω
- Conversion accuracy: 0.1% F.S. (25°C ± 2°C)
- Temperature Drift: 40 ppm/°C
- Response time: ≤500 ms
- Electromagnetic Compatibility: IEC 61326-3-1
- Dielectric strength: ≥2500 VAC (between intrinsically safe side and non‑intrinsically safe side); ≥1500 VAC (between power supply and non‑intrinsically safe side)
- Insulation resistance: ≥100 MΩ (input/output/power supply)
- Operating temperature: -20°C to +60°C
- Storage temperature: -40°C to +80°C
- Dimensions: Width 12.7 mm × Height 110 mm × Depth 118.9 mm
- Output status: Unless otherwise specified by the user, the output will track changes in the input signal across the full‑scale range, regardless of any fault conditions in the input. (Exception: when the 4–20 mA line is open, the output will be 0 V or 0 mA.) However, the output shall not exceed 110% of the upper limit of the output range. For example, with a 0–20 mA output, the minimum output may be 0 mA, and the maximum shall not exceed 22 mA.
- Application: Installed in a safe area, it can be connected to intrinsically safe equipment in Zones 0, 1, and 2; for gas groups IIA, IIB, and IIC; and for temperature classes T1 through T6.
