Why Engineers Specify This Model
- API 670 Compliance: Meets the industry standard for machinery protection systems, satisfying EPC contractor and end-user specifications without additional engineering waivers.
- High-Channel Density: The 16-channel configuration reduces rack footprint and wiring cost compared to single- or dual-channel alternatives.
- Seamless System 1 Integration: Native compatibility with Baker Hughes System 1 Evolution software enables real-time trending, alarm management, and predictive analytics without third-party middleware.
- Proven Field Reliability: The 3500 platform has accumulated decades of runtime in the harshest rotating-equipment environments globally, with a documented MTBF exceeding 100,000 hours.
- Configurable Alarm Architecture: Alert and danger setpoints are independently configurable per channel, supporting both absolute and differential vibration limits per API 670 Table 1.

Application-Specific FAQ
Q: Is the 21000-16-05-00-030-04-02 compatible with older 3500 racks?
A: Yes. The module is backward-compatible with all 3500 Series 14-slot racks. Firmware version should be verified against the rack’s RIM firmware for full feature parity.
Q: Can this module monitor axial position in addition to radial vibration?
A: Yes. Each channel is software-configurable for radial vibration, axial position, differential expansion, or eccentricity measurement, depending on the connected probe type and driver.
Q: What is the difference between the -030 and -060 gap voltage options in the part number?
A: The -030 suffix indicates a nominal gap voltage of -3.0 VDC (optimized for 3300 XL 8mm probes), while -060 is calibrated for 11mm probe systems. Mismatching gap voltage to probe type will result in out-of-range readings and nuisance trips.
Q: Does Konmask.com provide a warranty on surplus Bently Nevada modules?
A: Yes. All tested surplus units carry a 12-month functional warranty. New-surplus units carry the original OEM warranty where applicable. Terms are provided with each quotation.
Q: Can I integrate this module with a third-party DCS such as Honeywell Experion or Emerson DeltaV?
A: Yes, via the 3500/92 Communication Gateway Module using Modbus TCP/RTU or OPC-DA/UA. Direct hardwired 4–20 mA outputs are also available for legacy DCS analog input cards.
