Description:

The GSI127 is a galvanic separation unit from Meggitt’s vibro-meter product line. It 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 too), the IQS9xx signal conditioners used by TQ9xx proximity sensors (and older IQS4xx signal conditioners too), 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) vibration sensors, that is, the integrated electronics used by constant-current voltage output sensors such as the CE620 and PV660 (and older CE680, CE110I and PV102. sensors too).
The GSI127 galvanic separation unit is a versatile unit that can is 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. More generally, it may be used to supply any electronic system (sensor side) having a consumption of up to 22 mA.
The GSI127 also rejects a large amount of the frame voltage that can introduce noise into a measurement chain. (Frame voltage is the ground noise and AC noise pickup that can occur between the sensor case (sensor ground) and the monitoring system (electronic ground) ). In addition, its redesigned internal power supply results in a floating output signal, eliminating the need for an additional external power supply such as an APF19x.

The GSI127 is certified to be installed in an Ex Zone 2 (nA) when supplying measurement chains installed in Ex environments up to Zone 0 ( [ ia ] ). The unit also eliminates the need for additional external Zener barriers in intrinsic safety (Ex i) applications.

The GSI127 housing features removable screw terminal connectors that can unplugged from the main body of the housing to simplify installation and mounting. It also features a DIN-rail mounting adaptor that allows it to be mounted directly on a DIN rail.

Ordering Information: GSI127 Galvanic Separation Unit
To order this product, please specify the Type, Designation, and the specific Part Number (PNR) derived from the configuration options below.
Base Ordering Number (PNR): 244-127-000-021

1. Environment Options (A)
Select the version based on the installation environment:
Standard: For use in non-hazardous areas; features a completely gray housing.
Explosive (Ex): Certified for use in potentially explosive atmospheres (Hazardous Areas). The housing is gray with a blue screw-terminal connector for sensor-side signals.

2. Transfer Function Options (B)
Choose the option code that matches your specific measurement chain or sensor type:

Option Code (B)	Sensitivity	Zero (Offset)	Typical Application / Compatibility
01	Standard	$5\text{ mA} \rightarrow 7\text{ V}$	vibro-meter® CExxx sensors with current output
02	1V/mA	$12\text{ mA} \rightarrow 7\text{ V}$ $12\text{ mA} \rightarrow 7\text{ V}$	IPCxxx signal conditioners or VE210 sensors with current output
03	3.2V/mA	15mA→0V	IQS90x (or IQS4xx) conditioners with current output
04	1V/V	---	IPCxxx signal conditioners with voltage output
05-	-1V/V	---	IQS90x, IQS4xx, or VE210 with voltage output
11	0.5V/mA	---	IQS91x or industry-standard 4 to 20 mA loop-powered sensors
21	1V/V	---	Industry-standard IEPE sensors (e.g., CE620, CE630, PV660)

1. Only CExxx piezoelectric accelerometers with a current output signal require a GSI127. For example, the CE134, CE281 and CE31x.

2. An IPCxxx signal conditioner or a VE210 velocity sensor with a current output signal is typically used for signal transmission over longer distances.Note: For an IPC707 without diagnostics, the nominal current output signal (DC) is 12 mA (→ 7 V). For an IPC707 with diagnostics, the nominal current output signal (DC) is 13 mA (→ 8 V). Refer to the IPC707 signal conditioner data sheet for further information.
3. An IQSxxx signal conditioner with a current output signal is typically used for signal transmission over longer distances.
4. An IPCxxx signal conditioner with a voltage output signal is typically used for signal transmission over shorter distances.Note: For an IPC707 without diagnostics, the nominal voltage output signal (DC) is 7 V. For an IPC707 with diagnostics, the nominal voltage output signal (DC) is 8 V. Refer to the IPC707 signal conditioner data sheet for further information.
5. An IQSxxx signal conditioner or a VE210 velocity sensor with a voltage output signal is typically used for signal transmission over shorter distances.
6. For use with industry standard IEPE (integrated electronics piezo electric) vibration sensors, that is, constant-current voltage-output sensors such as the CE620 and PV660 (and older CE680, CE110I and PV102 sensors).
