Bently Nevada 133323-01 Modbus RS485 I/O Module
The Modbus RS485 rear I/O module for the Bently Nevada 3500/92 Communication Gateway.
Product Profile
Bently Nevada 133323-01 is the Modbus RS485 I/O module listed for the 3500/92 Communication Gateway.
The companion front gateway module is 136180-01. The rear I/O selection establishes the physical serial interface and therefore must match the field network rather than a different RS232/RS422 or Ethernet execution.
Gateway replacement should retain the address map, communications settings, cable topology and host-system test record.

System Role
Export the communication map
Record Modbus address, baud rate, framing, register use and gateway configuration.
Trace the serial segment
Capture polarity, shield, termination, biasing and every network node before disturbance.
Validate end-to-end exchange
Confirm gateway diagnostics and every required value at the Modbus master after service.
Compatibility
RS485 field interface
The rear module provides the RS485 physical layer for the associated Modbus gateway.
Paired gateway assembly
133323-01 is recorded with the 136180-01 front communication module.
Variant-controlled selection
Other 3500/92 I/O modules use different serial or Ethernet interfaces.
Configuration traceability
Device address, baud rate, framing and register use belong to the service file.
Applications
DCS data exchange
Sending selected 3500 rack data to a Modbus master over an RS485 network.
Legacy serial integration
Maintaining a multi-device serial segment whose electrical interface is already documented.
Gateway spare preparation
Separating the rear RS485 I/O module from other 3500/92 communication variants.

FAQ
Which front module is paired with 133323-01?
Bently Nevada lists 136180-01 as the 3500/92 Communication Gateway front module.
What makes 133323-01 different from 125736-01?
133323-01 is the RS485 I/O module, while 125736-01 is the RS232/RS422 rear I/O execution.
What network details should accompany a 133323-01 enquiry?
Provide the gateway label, node address, baud rate, framing, topology, termination and terminal photographs.
Should 133323-01 be replaced before the register map is saved?
No. Retain the gateway configuration and the host register map before changing the physical interface hardware.
What proves 133323-01 is communicating after service?
Require normal gateway status and verified end-to-end values, alarms and quality states at the Modbus master.
