Product Detail

Dedicated rear wiring card matched with front overspeed module 133388-01, accesses Keyphasor probe signals and outputs trip/alarm hard contacts to ESD, complies with API 670 for turbine/compressor overspeed protection, tested surplus spare parts

Product Overview

PN: 133396-01
Brand: Bently Nevada (Baker Hughes)
Series: 3500 Machinery Protection TSI System
Type: 3500/53 Electronic Overspeed Detection Rear I/O Module
Function: Exclusive rear termination board paired one-to-one with front module 3500/53 133388-01. It provides field wiring terminals for Keyphasor proximity probes or magnetic pickup speed sensors, transmits pulse speed signals to the front acquisition card; meanwhile outputs overspeed alarm and emergency trip relay dry contacts to external ESD shutdown system, DCS and interlock circuit. It is the only matching rear card to complete the whole overspeed protection channel, supporting 2-out-of-2 dual redundant or 2-out-of-3 TMR triple redundant safety voting architecture.

Core Features

Integrated multi-channel signal input terminals for speed sensors and isolated relay output terminals for trip interlock
Front-rear card strictly paired installation inside the same rack slot, supports hot swapping under dual redundant rack power supply
Built-in signal surge suppression and EMI filtering circuit, adapts to strong electromagnetic interference in power and petrochemical control rooms
Screw locking terminal blocks to prevent loose wiring caused by equipment vibration during long-term unit operation
All overspeed trip hardwired signals are directly output via this rear card, independent of rack communication bus to guarantee safety interlock reliability

Technical Specifications

Supported Input Sensors: 3300XL eddy current proximity probe, magnetic pickup transducer
Output Contact Type: Isolated trip/alarm relay contacts
Input Signal Range: -24V ~ +10V
Operating Temperature: -40℃ ~ +70℃
Net Weight: 0.5kg
HS Code: 8538900000
Certifications: CE, SIL2 functional safety certification
Product Status: Discontinued, brand new original & fully tested surplus modules available

Compatibility

Mandatory Matching Front Module: 3500/53 front card 133388-01
Applicable Rack: All standard 3500/05 series 12-slot & 14-slot monitoring chassis
System Requirement: The rack must be equipped with dual redundant 3500/15 power supply modules when using 3500/53 overspeed group
Upper External Equipment: ESD emergency shutdown system, DCS distributed control system, on-site alarm annunciator
Not Compatible: Other series rear I/O boards, non-3500 third-party rack chassis

Application

Signal wiring and trip output terminal unit for steam turbine, gas turbine and centrifugal compressor overspeed protection subsystems
Realize hard-wired emergency shutdown protection to avoid rotor damage caused by unit overspeeding
Spare replacement and overhaul retrofit of legacy 3500 TSI overspeed monitoring protection racks
