125736-01 is the manufacturer-listed Modbus RS232/RS422 rear I/O module for the Bently Nevada 3500/92 Communication Gateway. It provides the serial field interface used when rack values, module status and alarm status must be exchanged with a process-control or automation host through Modicon Modbus RTU.
125736-01 works with the 3500/92 gateway module at the front of the rack; it is not a complete communication gateway by itself. For an engineering replacement or a new quotation, the selected serial medium, cable route and host interface should be confirmed before the I/O module is ordered.
Serial-interface choiceProvides the official RS232/RS422 I/O option for a 3500/92 gateway configuration. |
Rack-data pathwaySupports serial Modbus RTU transfer of measured values, module status and alarm status collected by the gateway. |
Rear-slot integrationOccupies one full-height rear rack slot behind the associated 3500/92 module. |
Official fact: 125736-01 is the RS232/RS422 version, while 133323-01 is the RS485 version. Engineering consequence: selecting the wrong rear I/O module can leave the host cable and electrical interface incompatible. Action: confirm the host port and required serial standard before quotation or installation.

List it as the rear Modbus RS232/RS422 I/O module and identify the associated front gateway as a separate system component.
Identify whether the host requires RS232 or RS422, the connector pinout, cable route, and communication distance. Match the electrical interface before ordering.
Check the selected standard, pinout, shielding, grounding, connector condition, and total route length against both the gateway and host drawings.
Verify interface mode, Modbus RTU settings, node addressing, cable pinout, and the 3500/92 communication indicators before exchanging plant data.
The field link may use the wrong serial standard, exceed its distance boundary, or have shielding, grounding, or termination faults. Check the physical layer before changing the gateway map.
Provide the front gateway number, required RS232 or RS422 interface, cable length and connector, quantity, condition, destination, and clear labels.
Technical identity and product facts were checked against 3500/92 Communication Gateway Datasheet, 141542 Rev. N. Verify the installed nameplate, revision, companion module and project documentation before commissioning.
