Product Details
- Product Description

Product Introduction
The current‑sensing safety barrier provides an isolated power supply to 2‑wire and 3‑wire transmitters in hazardous areas while simultaneously monitoring the transmitter’s output current. It then isolates and transmits either the current or voltage signal to a safe area, and supports bidirectional HART digital communication. This product requires independent power supply and features three‑terminal isolation between input, output, and power.
Technical Specifications
- Power Supply: 18V DC to 32V DC, with reverse polarity protection.
- Operating power consumption: 2.5 W
- Input signal: 4–20 mA, HART digital signal
- Input impedance: approximately 75 Ω
- Distribution voltage: Open-circuit voltage ≤ 26 V; at 20 mA, output voltage ≥ 15.5 V.
- Output signal: 4–20 mA, with or without a HART digital signal
- Permissible load: Active: RL ≤ 500 Ω; Passive: RL < [(U − 3) / 0.02] Ω; where U is the loop supply voltage. Conversion accuracy: 0.1% F.S. (25°C ± 2°C).
- Temperature Drift: 40 ppm/°C
- Response time: ≤2 ms
- Electromagnetic Compatibility: IEC 61326-3-1
- Dielectric strength: ≥2500 V AC (between intrinsically safe and non‑intrinsically safe sides); ≥1500 V AC (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 17.7 mm × Height 110 mm × Depth 118.9 mm
- Application: Installed in hazardous areas, 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.
