General

  • Manufacturer GE / Bently Nevada
  • Model 135489-03
  • Condition New Original ready stock
  • Product Family 135473-01,143489-01,176449-02
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Sensor Selection: In the software's "Sensor" tab, the Velomitor type must be selected. Since the 135489-03 integrates safety barriers, the software will automatically match the corresponding electrical compensation parameters.
  • Channel Pairing: This module supports 4 independent channels. During configuration, you can define them as radial vibration, axial displacement (application-specific), or reciprocating machine impact monitoring.
  • Alarm Settings: Alert and Danger thresholds, as well as delay times, are set via software. These logics are then sent to the corresponding upstream monitoring modules.
  • Hardware Switch: Check the write protection switch on the back of the 3500 frame. It must be set to the "On" state for successful configuration.
  • Passive Attribute: The 135489-03 is a physical interface board and does not contain independently updatable firmware.
  • Related Updates: The so-called "firmware update" actually refers to updating the firmware of its paired 3500/42M or 3500/70M master module.
  • Operation Method: Connect the 3500/22M (TDI) module to the PC. Use the Firmware Upgrade Utility in the configuration software. Select the corresponding Slot to update.
  • Note: Updating the firmware will temporarily disable the monitoring channel to which the module belongs. It is recommended to perform this update while the equipment is powered off.
  • Hazardous Areas: Due to its integrated internal safety barrier, it allows direct connection of Velomitor sensors located in Zone 0, Zone 1, or Zone 2 (Class I, Div 1/2) without the need for an external safety barrier cabinet.
  • Large Rotating Machinery: Commonly used for monitoring the casing vibration of steam turbines, centrifugal compressors, pumps, and fans (using Velomitor to measure velocity values ​​and convert them to displacement).
  • Reciprocating compressors: When used with the 3500/70M module, it monitors crosshead impact or compressor vibration to identify loose connecting rods or valve malfunctions.
  • Space-constrained installation: For control cabinets without space to install external isolation barriers, this integrated I/O module is the preferred solution.
Description
The Bently Nevada 135489-03 I/O module is a specialized component designed for the 3500 series system, offering four dedicated Velomitor velocity sensor channels with typical amplitude accuracy of ±1% and a bandwidth up to 30 kHz. Unlike other modules such as 135489-01 or 135489-02, which may offer mixed or fewer channels, 135489-03 provides full 4-channel capability, ensuring comprehensive monitoring for both 3500/42M and 3500/70M applications.

Equipped with internal barriers and terminations, 135489-03 enhances safety and simplifies wiring in hazardous areas. Its operating temperature range of -30°C to +65°C and storage range of -40°C to +85°C, along with 95% non-condensing humidity tolerance, ensures reliable operation even in extreme industrial environments. In comparison, modules like 135489-01 and 135489-02 may have more limited environmental specifications, making 135489-03 more robust for demanding installations.

The module is fully compatible with 3500/42M Proximitor/Seismic Monitors and 3500/70M Recip Impulse/Velocity Monitors, providing flexibility for system upgrades or expansions. While the core hardware of 135489-03 is identical across both monitor types, the specific measurement function—whether radial vibration for 3500/42M or reciprocating compressor impulse/velocity for 3500/70M—is determined by the main monitor module and system configuration software, giving operators precise control over monitoring objectives.

Compared to other I/O modules in the 3500 series, 135489-03 stands out for its pure Velomitor support, full 4-channel design, and built-in safety features. This makes it ideal for installations where consistent signal fidelity, simplified integration, and hazardous-area compliance are critical. Its interchangeability between 3500/42M and 3500/70M modules ensures long-term flexibility and reduces inventory complexity for operators managing multiple 3500 series systems.

In summary, Bently Nevada 135489-03 is the go-to I/O module for advanced 3500 system installations that require high-accuracy Velomitor inputs, safe internal wiring, and compatibility across multiple monitor types, outperforming similar modules like 135489-01 and 135489-02 in channel capacity, environmental tolerance, and flexibility.
