        Overview Manuals Relay Selection Wiring & Safety Installation Application
        • Provides the standard rear I/O assembly for 16 relay outputs in a compatible 3500/33 module
        • Uses epoxy-sealed SPDT silver-contact relays with a standard 250 Vrms arc suppressor
        • Organizes the channels into four switch-selectable groups for normally de-energized or normally energized operation

        Bently Nevada 3500/33 149992-01 is a spare 16-channel relay output module designed for the Bently Nevada 3500 machinery protection system.

        It occupies the full-height rear I/O position and works with the separate 149986-01 front relay control module to connect programmable Alarm Drive Logic to field relay contacts.

        Before installation or replacement, verify the installed output variant, front control module, ND/NE switch pattern, contact load, field wiring, and hazardous-area or functional-safety restrictions.

        Availability, condition, price, and shipping time for Bently Nevada 3500/33 149992-01 are confirmed during quotation.

        • Part 149992-01 is the standard silver-contact output module; failsafe and low-current versions use different spare numbers
        • The standard contacts require a minimum load of 100 mA at 5 V DC and are rated for resistive AC or DC loads
        • Each group of four relay channels is switch-selectable for normally de-energized or normally energized operation
        • Disconnect power before servicing because field conductors may expose hazardous voltage
        • A 250 Vrms relay arc suppressor is installed as standard on the output module
        • Hazardous-area, failsafe, and functional-safety installations can impose lower allowable switched-voltage limits
        • The 149992-01 output module occupies one full-height rear slot behind a compatible 3500/33 control module
        • The completed 3500/33 can be installed in rack slots to the right of the Transient Data Interface module
        • 3500 Rack Config version 3.3 or later is required to program the associated Alarm Drive Logic
        • Relay actuation from Alert and Danger states in 3500 machinery protection racks
        • Protective interlocks driven by the Not-OK state of monitored channels

        Description
        Bently Nevada 3500/33 149992-01 is a spare 16-channel relay output module for the Bently Nevada 3500 System.

        The rear I/O module provides 16 epoxy-sealed SPDT standard relays with silver contacts, a 250 Vrms arc suppressor, and four switch-selectable groups for normally de-energized or normally energized operation.

        Before installation or replacement, confirm the separate 149986-01 relay control module, standard-versus-failsafe and standard-versus-low-current selection, rear-slot wiring, switch positions, contact load, and hazardous-area approval requirements.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        Does Bently Nevada 3500/33 149992-01 replace the front relay control module?
        No. Bently Nevada 3500/33 149992-01 is the rear 16-channel relay output/I/O module. The separate front relay control module is spare part 149986-01. A replacement order must identify which half of the 3500/33 assembly is required.
        Is Bently Nevada 3500/33 149992-01 interchangeable with 149992-02, 149992-03, or 149992-04?
        Not automatically. Part 149992-01 is the standard relay output module; 149992-02 is failsafe, 149992-03 is low-current, and 149992-04 combines low-current and failsafe behavior. Match the installed output type and safety design before substitution.
        When should a low-current alternative be selected instead of Bently Nevada 3500/33 149992-01?
        The standard silver contacts in 149992-01 require at least 100 mA at 5 V DC. For loads in the low-current region, Bently Nevada directs users to the gold-plated low-current output options. Confirm the actual field load before choosing the replacement.
        Why must the relay mode switches be recorded before replacing Bently Nevada 3500/33 149992-01?
        Its 16 channels are divided into four groups of four, with each group switch-selectable for normally de-energized or normally energized operation. Copying the original switch pattern prevents unintended reversal of alarm or trip behavior.
        Can Bently Nevada 3500/33 149992-01 be commissioned without a compatible front module and rack configuration?
        No. The rear output module supplies the physical relay contacts, while the compatible 149986-01 front control module executes the programmed Alarm Drive Logic. The completed 3500/33 also requires 3500 Rack Config version 3.3 or later.
        What hazardous-voltage precautions apply when wiring Bently Nevada 3500/33 149992-01?
        Field conductors can expose hazardous voltage. Disconnect power before servicing and never disconnect a live circuit unless the area is known to be non-hazardous. Observe the lower 30 V limit where failsafe, hazardous-area, or functional-safety restrictions apply.
        What should be investigated if a relay connected through Bently Nevada 3500/33 149992-01 does not change state?
        Check the paired 149986-01 module, Alarm Drive Logic, rack communication, ND/NE group switch, field supply, contact load, and NO/NC/ARM wiring. Also verify that the replacement is the standard 149992-01 rather than a different failsafe or low-current output variant.
