Meggitt Vibro-Meter GSI127 244-127-000-017-A2-B03 Galvanic Isolation Unit

Product Description

The GSI127 244-127-000-017-A2-B03 is a DIN-rail mounted galvanic separation unit from Meggitt Vibro-Meter, used for vibration sensor signal isolation and power supply. It provides galvanic isolation between IEPE accelerometers, proximity probes, charge amplifiers and the monitoring rack, eliminates ground loop noise, and converts sensor signals for MMS6000 / VM600 online vibration monitoring systems. A2-B03 is the configuration suffix defining certification, signal output and terminal variant.

FAQ

Q: What is the difference between A2-B03 and other suffixes like A1-B02?
A: The suffix A/B codes define explosion-proof type, signal output range and terminal block layout; core isolation function is consistent.

Q: Can GSI127 work with Bently Nevada 3500 system?
A: It can isolate IEPE sensor signals and output 4-20mA, but it is originally designed for Vibro-Meter monitoring racks, not direct native interface for 3500 proximity channels.

Q: What is the replacement part for GSI127 244-127-000-017?
A: The updated part number is 244-127-000-021, pin-to-pin compatible for most configurations.
