ASGEXA-G91
- Commodity name： ASGEXA-G91
- Input： 2-wire and 3-wire potentiometers, 0 kΩ to 10 kΩ
- Number of channels： One in, one out
- Output： 4–20 mA
- Power supply mode (both can be centralized power supply)： 24VDC

Product Introduction
The potentiometer input safety barrier isolates and converts two‑wire and three‑wire potentiometer signals from the hazardous area into current‑signal outputs, which are then transmitted to the safe area. This product requires an independent power supply and features three‑terminal isolation between the input, output, and power supply. It includes built-in online fault self‑diagnosis and allows users to configure the potentiometer’s zero point and full scale, as well as the output behavior in the event of a signal fault, via a PC or a handheld programmer.
Technical Specifications
- Power Supply: 18 VDC to 32 VDC, with reverse polarity protection.
- Operating power consumption: 0.7 W (24 V, single-channel full-load output); 1.3 W (24 V, dual-channel full-load output)
- Input signal: 2-wire and 3-wire potentiometers, 0 kΩ to 10 kΩ
- 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: 12.7 mm wide × 110 mm high × 118.9 mm deep
- 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 signal (except for open‑circuit conditions, where the output is 0 V/mA). However, the output shall not exceed 110% of the upper limit of the output range; for example, with a 0 mA to 20 mA output, the minimum output may be 0 mA, and the maximum shall not exceed 22 mA.
- 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.
