Product Description
VIBRO METER GSI 127 244-127-000-017 A2-B02 Galvanic Separation Unit
The GSI127 galvanic separation unit is designed for use with a wide range of signal conditioners, charge amplifiers, and electronics in various measurement chains and sensors. Compatible devices include IPC707 signal conditioners (and older IPC704) for CAxxx piezoelectric accelerometers and CPxxx dynamic pressure sensors, IQS9xx signal conditioners (and older IQS4xx) for TQ9xx proximity sensors, electronics used by CExxx piezoelectric accelerometers, and integrated electronics of the VE210 velocity sensor. The GSI127 also supports industry-standard IEPE vibration sensors, including constant-current voltage output sensors such as CE620 and PV660 (and older CE680, CE110I, PV102).
This versatile unit transmits high-frequency AC signals over long distances in measurement chains using current-signal transmission or serves as a safety barrier in voltage-signal transmission chains. It can supply any electronic system (sensor side) consuming up to 22 mA. The unit rejects a large portion of frame voltage, reducing noise caused by ground differences between the sensor case and monitoring system. Its redesigned internal power supply provides a floating output signal, eliminating the need for additional external power supplies such as the APF19x.
Designed for industrial and hazardous environments, the GSI127 is certified for installation in Ex Zone 2 (nA) while supplying measurement chains in Ex Zone 0 ([ia]). It removes the need for additional Zener barriers in intrinsic safety (Ex i) applications. The housing features removable screw-terminal connectors for simplified installation and mounting, along with a DIN-rail mounting adaptor for direct attachment to DIN rails.

What does it actually do?
So, in plain English, what's the GSI 127 actually for?
Think of it as the middleman that keeps everyone safe. It acts as a power supply and a galvanic separator. Basically, it powers your sensors (like vibration transmitters) while making sure the signal side and the monitor side aren't touching electrically. It prevents ground loops and noise from messing up your data.
I've got a mix of sensors. Will this thing play nice with them?
Most likely, yes. It's pretty versatile. It loves industry-standard stuff like IEPE sensors and those common 4-20 mA loop-powered sensors. If you're doing vibration monitoring, this unit is built exactly for that.
Hazard & Safety
Can I stick this in a hazardous area?
Absolutely. It's fully certified for potentially explosive atmospheres (Ex areas). You don't need to worry about it being the spark that starts a fire.
My project requires SIL 2 compliance. Does this make the cut?
Yep, it checks that box. It's suitable for functional safety contexts and is rated SIL 2 according to IEC 61508. It's not just a converter; it's safety gear.
Part Number Check
I'm looking at part number 244-127-000-017 A2-B02. Is that the one?
That's the specific config for the GSI 127 Galvanic Separation Unit we're talking about. If those numbers match your spec sheet, you've got the right hardware for high-isolation, Ex-certified vibration monitoring.
We know how it goes. You have a system down, the part is "obsolete," and the original manufacturer says the lead time is 6 months. That's where Amikon steps in.
We act as the bridge between you and the parts you need right now. We are a stocking distributor with over 1 million items ready to go. We specialize in helping system integrators and suppliers avoid those nightmare shortage scenarios.
Why trust us?
We partner directly with the big players (Tier 1 companies) to source both new and discontinued machinery.
Need it fast? We ship immediately.
Need it safe? We offer a full warranty.
