Vibro-Meter GSI127 244-127-000-017-A2-B01 Galvanic Separation Unit

GSI127 244-127-000-017-A2-B01 has the B01 option for CExxx accelerometers with a current output; the manufacturer cites CE134, CE281 and CE31x as examples. Verify the installed sensor output before replacement.

GSI127 244-127-000-017-A2-B01 uses B01: 1 V/mA with 5 mA corresponding to 7 V. B02 uses a different current reference, while B21 is for voltage-output IEPE sensors; these options are not signal-equivalent.

GSI127 244-127-000-017-A2-B01 uses the A2 Ex option. The datasheet permits the unit in Ex Zone 2 while it supplies approved measurement chains up to Zone 0, subject to the relevant certificate and installation conditions.

GSI127 244-127-000-017-A2-B01 mounts on a TH 35 DIN rail and requires 18 to 30 VDC. Its removable top four-contact connector is for sensor-side signals and its bottom four-contact connector is for monitor-side signals; follow the official terminal diagram.

GSI127 244-127-000-017-A2-B01 has 1 V/mA ±1% B01 sensitivity. At the specified 5 mA current-input reference, the monitor output is 7 VDC ±200 mV; use the approved site test procedure.

GSI127 244-127-000-017-A2-B01 transfers from DC to 20 kHz within ±0.5 dB and provides 4 kVRMS sensor-to-monitor isolation plus 50 VRMS power-to-output isolation.

GSI127 244-127-000-017-A2-B01 is built from base 244-127-000-017, A2 for Ex environment and B01 for the CExxx current-output transfer. Match all three parts of the code and the applicable Ex certification.
