Functional Highlights
– Integrated IS barriers – internal 91 Ω / 50 V network allows direct connection of Zone 0 proximity probes without external safety relays
– Flexible measurements – each channel programmable for radial vibration, thrust position, eccentricity, differential expansion or REBAM
– Dual alarms – independent Warning and Danger set-points per channel with programmable delays and latching logic
– OK status – continuous verification of sensor, cable and monitor integrity; relay driven into safe state on fault
– Hot-swap – insertion/extraction under power without interrupting rack operation or protection
– Field firmware – upgrade via System 1 or Ethernet in <3 min; rollback image stored for safety
– TMR ready – certified for Triple Modular Redundant racks where 2-out-of-3 voting is required
– Asset management – onboard diagnostics report probe gap, signal level, cable integrity and module health over the same network link
Application Scenarios
– Steam & gas turbine TSI cabinets – monitor shaft radial vibration and thrust position to prevent blade contact or bearing wipe
– Offshore platform centrifugal compressors – protect against surge-induced axial movement and high radial vibration in Zone 1 areas without external barriers
– LNG refrigeration trains – detect mis-alignment and imbalance in multi-stage compressors while meeting ATEX requirements
– Ethylene hyper-compressors – monitor rod-drop and cross-head vibration for early rider-ring wear detection
– Cross-country pipeline pump stations – protect motor-driven pumps from cavitation and bearing failure in Class I Div 2 locations
– Steel mill blast-furnace blowers – measure gearbox housing vibration to prevent tooth breakage
– Wind-turbine test stands – track nacelle acceleration and main-bearing displacement for modal analysis
– Nuclear feed-water pumps – TMR configuration meets IEEE 338 requirements for safety-related vibration monitoring
Installation & Maintenance
The card plugs onto the rear of the 3500/40M monitor; rising-clamp terminals accept 0.2 – 2.5 mm² field wires.
Front LEDs on the monitor indicate channel health, alarm status and OK state.
Probe gap voltage and signal amplitude are continuously monitored; alarms are generated for open or shorted cables.
Replacement takes <1 min; all rack parameters remain stored non-volatilely on every monitor, so no re-configuration is necessary.
Compatibility
Backward- and forward-compatible with every 3500/40M monitor main card.
Supported by System 1 v6.5 onward and by third-party OPC UA, Modbus and DNP3 clients.
