Product information

PLC Automation Controller | 20 Years of Industrial Automation Supply Experience

BENTLY NEVADA |3500/33 149986-01 | 16-channel relay module


What it is

The 3500/33 149986-01 is a full-height, 16-channel relay module that plugs directly into any 3500 rack.

Each SPDT contact is driven by configurable AND/OR alarm logic, converting vibration, thrust, temperature or speed alarms from any 3500 monitor into isolated control signals for plant safety systems, DCS/PLC interlocks, annunciators or machine trip circuits. The module is hot-swappable and SIL-rated, providing the final “execute” layer of Bently Nevada’s API 670-compliant machinery protection suite.


Technical Specifications

Parameter

Specification

Channels

16, individually programmable

Contact type

SPDT (Form C)

Contact rating

2 A @ 24 VDC / 24 VAC; 5 A @ 250 VAC resistive

Operate time

< 8 ms (pick-up)

Release time

< 4 ms (drop-out)

Isolation

1 500 Vrms channel-to-ground & channel-to-channel

Logic functions

AND, OR, voting, latching, inversion per relay

LED indicators

16 red/green LEDs (relay state & coil health)

Back-plane power

24 VDC via 3500 rack, 0.3 W per relay (4.8 W max)


· Key Benefits

Ø High-density tripping – 16 independent relays in one slot cuts panel space and wiring by 50 %.

Ø SIL 2 / API 670 logic – certified for safety-critical machine trip circuits and plant interlocks.

Ø Sub-10 ms response – fastest pick-up time in class for turbo-machinery overspeed or thrust-trip protection.

Ø Flexible alarm math – combine any monitor channel with AND/OR voting to eliminate false trips during start-up.

Ø Hot-swap maintenance – front LEDs show relay and coil health; swap modules on-line without rack power-down.

Ø Multi-voltage contacts – same relay drives 24 VDC solenoids, 120 VAC annunciators or 250 VAC motor contactors.

Ø Hardened for extremes – conformal coating and –20 °C rating suit offshore, desert and arctic installations.


Applications

Gas & steam turbines – machine trip, fire-fuel shut-off and emergency lube-oil start on overspeed or high thrust.

Centrifugal compressors – antisurge valve open and motor shutdown on high vibration or low flow.

Generators – field-breaker trip and exciter disable on rotor eccentricity or stator temperature alarm.

Refinery pumps – process isolation and spare-pump start on bearing temperature or seal failure.

Fans & blowers – damper close and motor coast-down on blade-pass vibration or motor overload.

Test cells & rigs – activate dynamometer brake and alarm horn when any monitored parameter exceeds SIL limits.
