Key Functional Characteristics
Signal Integrity and Isolation
The GSI127 module offers superior Power Supply Rejection Ratio (PSRR). It stabilizes signals across a wide frequency spectrum. The floating output design supports a dynamic range of 2 to 20 VDC. This ensures accurate data for critical machinery protection.
Intrinsic Safety and Protection
This unit supports Zone 0 and Zone 2 hazardous area applications. It provides intrinsic safety without requiring separate Zener barriers. The internal architecture protects the sensor-side current up to 22 mA. This reduces overall system complexity and installation costs.
