GSI127 244-127-000-017 A2-B02 Galvanic Separation Unit
Key Features
High-level electrical isolation: Provides 4 kV RMS isolation between sensor and monitoring sides, and 50 V RMS isolation between power supply and output signal
Intrinsic safety certification: Holds ATEX and IECEx certifications; suitable for Zone 2 environments and capable of powering Zone 0 sensors
High interference immunity: Effectively suppresses rack voltage to ensure measurement signal accuracy
Flexible installation: Features standard DIN-rail mounting and pluggable screw terminals
Wide-bandwidth response: Supports signal transmission from DC to 20 kHz (±0.5 dB)
Status indication: Ex-certified versions feature blue terminals for easy identification
Product Description
The GSI127 244-127-000-017-A2-B02 is a high-performance galvanic separation unit designed to connect signal conditioners, charge amplifiers, and sensors within various measurement chains. It provides up to 4 kV RMS electrical isolation between the sensor side and monitoring side, effectively blocking ground loops and filtering out rack voltage interference of up to 50 V RMS, thereby ensuring signal integrity and stability.
Effectively eliminates ground loop noise and AC noise pickup
Explosion-proof certification
Suitable for Zone 2 installation; capable of powering Zone 0 devices
SIL 2 capability
Suitable for functional safety applications (IEC 61508)
Built-in diagnostics
Automatic remote indication of measurement chain health
Flexible configuration
Multiple sensitivity/zero-point options to suit various sensors
Easy installation
DIN-rail mounting + pluggable terminals
Wide operating temperature
-40°C to +85°C
High compatibility
Supports the full Vibro-Meter range and IEPE standard sensors
No external power supply required
Floating output design; eliminates the need for APF19x
Case Study
In the compressor monitoring system of an offshore natural gas platform, vibration sensors are mounted directly onto the compressor unit—an area subject to stringent explosion-proof requirements (Zone 0). The GSI127 A2-B02 unit is installed within a relatively safe control cabinet (Zone 2). It serves a dual purpose: providing intrinsically safe power to the IPC707 unit in the Zone 0 area and receiving the 4-20 mA vibration signal output by the IPC707. It converts this signal into a 7-19 V voltage signal and transmits it—via electrical isolation and without interference—to the downstream monitoring system and PLC, thereby ensuring both the safety of the monitoring loop and signal integrity within the hazardous environment.
Frequently Asked Questions
What distinguishes the GSI127 from standard isolators?
The GSI127 is a comprehensive signal interface module designed specifically for industrial vibration, pressure, and proximity measurement chains. It offers not only high-level electrical isolation (4 kVRMS) but also signal conversion capabilities (μA -> mV or V -> V), frame voltage suppression, built-in diagnostics, and explosion-proof certification.
What is the difference between the A2 and A1 versions?
The A2 is an explosion-proof (Ex) model suitable for potentially explosive environments, while the A1 is a standard model suitable for conventional industrial environments.
What malfunctions occur if the equipment's operating temperature exceeds 70°C?
Significant increases in zero-point and sensitivity thermal drift, leading to measurement errors exceeding specifications; extreme heat triggers internal overload protection, causing signal interruption. Ventilation and heat-dissipating rails must be installed to lower the temperature inside the cabinet.
What is the warranty period?
Standard industrial warranty: 12 months; with proper installation and no overloading, the product has a service life of 5-10 years.
