        • PRODUCT OVERVIEW

          What is this product?

          Bently Nevada 146031-01 is the copper Ethernet rear I/O module used with the 3500/22M Transient Data Interface in a 3500 machinery-protection rack. It provides an autosensing 10Base-T/100Base-TX connection through an RJ-45 connector and carries BN Host and BN TDI protocols over TCP/IP. Bently Nevada specifies IEEE 802.3 Ethernet operation and a maximum copper cable length of 100 m. In addition to network access, the rear module provides terminals for Trip Multiply, Alarm Inhibit and Rack Reset dry-contact inputs, the TDI OK relay, and the signal-common grounding connection. It occupies one full-height rear slot behind the associated TDI in rack slot 1. A correct replacement therefore requires the 146031-01 rear-module identity, installed 3500/22M TDI, RJ-45 network, rack-contact wiring, OK-relay selection and grounding arrangement to be checked together.

          Source boundary

          Official source: Bently Nevada 3500/22M Transient Data Interface Datasheet, document 161581. Part number 146031-01 identifies the rear 10Base-T/100Base-TX I/O module and does not by itself identify the TDI front module.
        • APPLICATIONS

          Where it may be used

          Use this rear I/O module only with the documented 3500/22M TDI configuration after confirming rack position, network medium, contact wiring and grounding.

          Copper TDI networking

          Connects the 3500/22M TDI to a 10/100 Ethernet network through the documented RJ-45 port.

          Host software link

          Carries BN Host and BN TDI protocols over TCP/IP within the specified 100 m cable limit.

          Rack contact access

          Provides Trip Multiply, Alarm Inhibit and Rack Reset dry-contact terminals for the installed rack.

          RIM-to-TDI upgrade

          Supports a documented TDI installation when network, relay, grounding and rack wiring are verified.

      Bently Nevada 146031-01 3500/22M Ethernet I/O module manual / Datasheet / Links Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

      The 146031-01 rear I/O module provides one autosensing copper Ethernet connection for the associated 3500/22M TDI. The documented interface supports 10Base-T and 100Base-TX in accordance with IEEE 802.3, using an RJ-45 connector and BN Host or BN TDI protocols over TCP/IP. Keep the installed copper run within the specified 100 m maximum and verify the host-network addressing and rack configuration before service.

      Install 146031-01 in the full-height rear slot associated with the 3500/22M TDI in rack slot 1. The rear I/O part number must be matched separately from the front TDI part number. During replacement, verify the rear connector seating, TDI compatibility, rack power isolation and ESD controls before restoring the rack to operation.

      Before transferring wiring, document the RJ-45 network cable, Trip Multiply, Alarm Inhibit and Rack Reset dry-contact terminals, TDI OK-relay conductors and the two-pin signal-common grounding connection. The contact inputs are dry contacts to common with less than 1 mA DC. Restore each conductor to the recorded terminal and confirm relay and grounding behavior after installation.

      Technical notes

      Bently Nevada 146031-01 is the copper Ethernet rear I/O module specified for the 3500/22M Transient Data Interface. It provides autosensing 10Base-T/100Base-TX communication through an RJ-45 connector using BN Host and BN TDI protocols over TCP/IP, with a documented maximum cable length of 100 m. The module also exposes Trip Multiply, Alarm Inhibit, and Rack Reset dry-contact inputs, an OK-relay interface, and the signal-common grounding connection. Confirm the associated TDI, rear-slot position, network wiring, rack-contact wiring, relay behavior, and grounding before replacement. Environmental limits in Bently Nevada document 161581 are -30 to +65 °C operating, -40 to +85 °C storage, and 95% non-condensing humidity.

      Rear Module Identity Review

      Confirm the complete rear-module marking 146031-01 and identify the associated 3500/22M TDI front module separately. Record the rack serial number, slot-1 front and rear labels, RJ-45 connector arrangement, rack-contact terminal wiring, OK-relay selection and signal-common connection. If any marking or module position is uncertain, provide clear nameplate and installed-rack photographs before a replacement is matched.
