Provides Ethernet and RS-485 physical connections for the paired 3500/92 gateway.
Product Identification
136188-02 is the Ethernet and RS-485 Modbus rear I/O module for the Bently Nevada 3500/92 Communication Gateway. It provides the physical network interfaces for the paired front gateway.
This item is not a stand-alone gateway and does not perform machinery-protection monitoring. The front 3500/92 module, rack configuration, firmware and host-network settings define the installed communication path.

Functions
Keeps plant communication wiring on the rear of the 3500 rack.
Supports access to configured rack values and status through the gateway communication path.
Separates network-interface hardware from the front gateway processing module.
Applications
- DCS, PLC or SCADA access to selected 3500 rack values through Modbus.
- Ethernet and serial host connections for machinery-condition information.
- Like-for-like replacement of the installed 3500/92 rear communication I/O.
- Maintenance of gateway wiring while preserving the front-module and register-map relationship.
Lifecycle
- Record the paired front-module part number, firmware, IP settings, serial settings and host register map before replacement.
- Label Ethernet, RS-485, shield and grounding connections before disturbing the rear I/O.
- Check switch ports, cable condition, polarity, termination, addressing and client polling before blaming the module.
- After installation, verify every Ethernet and serial client, mapped value, status and communication alarm.

FAQ
What front-module evidence is needed for a 136188-02 enquiry?
Provide the paired 3500/92 front-module part number, firmware, rack slot and clear front and rear label photographs.
Can 136188-02 operate without a 3500/92 front gateway?
No. It is the rear Ethernet/RS-485 I/O module and requires the matched front gateway.
What network data should be backed up before replacement?
Record IP configuration, switch port, RS-485 polarity, baud, parity, node address, termination and host register mapping.
Does 136188-02 perform machine protection?
No. It provides communication interfaces; the installed 3500 monitor modules continue to perform protection functions.
What proves the gateway path is restored?
Verify link status, Modbus polling, scaling, mapped values, status quality and alarms at every connected host.
