BENTLY 135489-04 Channel Displacement Module

Bently Nevada 135489-04 (3500/40M with explosion-proof built-in safety barrier rear card/channel displacement I/O terminal module)

135489-04 physical object

1、 Model positioning and definition
Complete set: front card motherboard 3500/40M (176449-01)+rear card terminal module 135489-04, the whole set is a 4-channel eddy current displacement monitoring card (Proximitor Monitor), commonly known as the “channel displacement module” in the industry
135489-04 suffix meaning
Built in intrinsic safety explosion-proof isolation safety barriers (Internal Barriers)
Comes with internal terminal wiring, no additional PIM terminal board required
Suitable for chemical explosion-proof Class I/II hazardous areas, probes and preamplifiers can be installed in the explosion-proof area
System ownership: Bently 3500 unit protection system, fully compliant with API 670 standard, used for monitoring shaft vibration/displacement of steam turbines and compressors
Discontinued status: The original factory standard 3500/40M complete set including 135489-04 has been mass-produced and is no longer being produced by the original factory. Only global inventory is consumed and maintenance services are provided
2、 Core Function (Function of Rear Card 135489-04)
Explosion proof safety barrier isolation
Built in intrinsic safety current and energy limiting barrier, 3300XL eddy current probe in explosion-proof area, 330180 preamplifier signal access, limiting energy to avoid ignition of oil and gas, Ex ia explosion-proof certification
4-channel probe signal terminal collection
Four coaxial terminals, connected to the 330180 series preamplifier output signal, to collect shaft radial vibration, axial thrust displacement, differential expansion, and eccentricity signals
Signal filtering and anti-interference
Built in RC filtering circuit to suppress on-site frequency converter and high-power motor power frequency interference, ensuring displacement measurement accuracy
Transfer of transmission output and alarm contacts
Transfer 4-channel isolated 4-20mA analog output (uploaded to DCS), module fault/channel alarm passive contacts
Hot swappable compatibility
Front and rear card separation design, the rear card 135489-04 can be replaced separately, and the rack is maintained without stopping the machine
3、 Complete 3500/40M (135489-04 matching front card) measurement capability
Single card with 4 channels, channels can be grouped and configured for measurement:
Radial axis vibration (μ m peak to peak value)
Axial thrust displacement (axial displacement)
Differential expansion of rotor and eccentricity of shaft
REBAM Rolling Bearing Fault Diagnosis
Each channel has independent Alert warnings and Danger two-level alarms, and can interlock 3500/34 triple redundant relays to achieve unit trip protection

5、 Differentiation of Rear Card Models in the Same Series (Selection Comparison)
table
Applicable scenarios for configuring the rear card part number
135489-01 No built-in safety barrier, ordinary terminal, ordinary factory non explosion proof area
135489-04 Built in intrinsic safety barrier+integrated terminal for oil refining and chemical explosion-proof hazardous areas (this version)
135489-02 External Safety Barrier Matching Terminal Independent External Safety Barrier Scheme
6、 Typical complete set of supporting equipment list
Monitoring front card: 3500/40M 176449-01 (4-channel main control)
Terminal Rear Card: 135489-04 (Explosion proof Safety Barrier Terminal Module)
Sensor system: 330103 probe+330130 extension cable+330180 preamplifier (as you previously inquired about 330180-51-00)
Rack matching: 3500/15 redundant power supply, 3500/20 framework interface module, 3500/92 communication gateway
7、 Key points of on-site operation and maintenance
Explosion proof scenarios must use 135489-04 and cannot be replaced by 135489-01 regular version, as the explosion-proof qualification is invalid;
The shielding layer of coaxial cable only controls the single end grounding on the cabinet side, and prohibits ground loop drift caused by grounding at both ends;
After replacement, there is no need to reconfigure the card, only the total length (5m/8m/10m) and sensitivity of the probe system need to be checked;
Current supply situation: New original inventory is scarce, and mainstream spare parts include disassembled test parts and refurbished whole cards, with a one-year warranty;
Cannot mix 3500/42M rear cards, 40M and 42M terminal board hardware are not compatible.
