GSI127 galvanic separation unit Vibro- Meggitt 

• Power supply and galvanic separation unit for sensors and/or signal conditioners with a current or voltage output.
• 4 kVRMS galvanic separation between the sensor side and the monitor side.
• 50 VRMS galvanic separation between the power supply and the output signal.
• μA to mV transfer function for long-distance signal transmission, V to V transfer function for short-distance signal transmission.
• Also compatible with industry-standard IEPE sensors and 4 to 20 mA loop-powered sensors.
• Certified for use in potentially explosive atmospheres (Ex) and/or safety-related applications (SIL).

PRODUCT INFORMATION

The GSI127 galvanic separation unit is designed for operation with the signal conditioners, charge amplifiers and electronics (attached or integrated) used by various vibro-meter measurement chains and/or sensors.

Compatible devices include the IPC707 signal conditioners (charge amplifiers) used by CAxxx piezoelectric accelerometers and CPxxx dynamic pressure sensors (and older IPC704 signal conditioners), the IQS9xx signal conditioners used by TQ9xx proximity sensors (and older IQS4xx signal conditioners), the attached or integrated electronics used by CExxx piezoelectric accelerometers, and the integrated electronics used by the VE210 velocity sensor. The GSI127 is also compatible with industry-standard IEPE (integrated electronics piezo electric) sensors such as the CE620, CE630 and PV660 vibration sensors, and 4 to 20 mA loop-powered sensors such as the CE687 and PV685 vibration sensors.

The GSI127 is a versatile device that can be used for the transmission of high-frequency AC signals over long distances in measurement chains using current-signal transmission or as a safety barrier unit in measurement chains using voltage-signal transmission. Further, it also rejects a large amount of the frame voltage that can introduce noise into a measurement chain. It has a factory-configurable transfer function (with variants defined by ordering option code) and provides a voltage output signal suitable for transmission to the monitoring system.

The GSI127 is designed and built for long-term use, and is available in standard versions and in Ex versions certified for use in potentially explosive atmospheres (hazardous areas). In addition, it incorporates diagnostics that automatically and remotely indicates the health/status of the measurement chain so you always know when measurements can be trusted. The diagnostics (SIL 2 “by design”) bring enhanced reliability and significant risk reduction, making the GSI127 suitable for use in safety-related applications (functional safety contexts).
