Description
Product Introduction & Engineering Value
When a 3500 rack must share real-time vibration, position, speed, and alarm data with a DCS or SCADA system, a dedicated gateway is required. The 13323-01 (3500/92 family) fills that role. It sits in the 3500 chassis, gathers data from the monitoring modules through the backplane, and presents it to higher-level systems using Modbus RTU or Modbus TCP.
The module is powered from the rack backplane, occupies a single slot, and supports both serial and Ethernet connections depending on configuration. It is the standard way to integrate 3500 protection data into plant-wide historians, asset-management platforms, or control systems without compromising the safety integrity of the monitoring rack.

Field Application & The “Trench” Experience
A power-generation plant needed to bring bearing vibration and thrust-position data from several 3500 racks into the existing DCS for operator display and long-term trending. The original serial gateway had become unreliable. Installing a tested 13323-01 module, configuring the Modbus map, and connecting it to the plant Ethernet network restored continuous data flow within a single outage window. Operators regained live values and alarm status without any change to the protection logic inside the 3500 racks.
Niche placements that fit this exact module:
- Bridging multiple 3500 racks to a central DCS or historian via Modbus TCP.
- Providing Modbus RTU data to older serial-based control systems still in service.
- Temporary or permanent gateway during migration from pure protection-only 3500 systems to integrated condition-monitoring platforms.

Transparency SOP: QA & Testing
- Visual inspection of the module, connectors, and faceplate for damage or corrosion.
- Installation in a powered 3500 rack; verification of backplane recognition and OK status.
- Serial and Ethernet port communication tests with known Modbus masters.
- Confirmation that live channel data and alarm status are correctly mapped and transmitted.
- Firmware version check and configuration backup/restore validation.
- Final functional burn-in under simulated data load followed by anti-static packaging.
The Veteran’s Tech Trap Guide
⚠️ Part-number variations – The gateway is frequently referenced as both 3500/92 and 13323-01 / 133323-01. Confirm the exact hardware revision and firmware against the existing rack configuration before installation.
⚠️ Slot and addressing – The module must be placed in an allowed slot and correctly addressed in the rack configuration. Incorrect placement or address conflicts will prevent data exchange.
PRO TIP: Always export and archive the full Modbus register map and rack configuration before swapping the gateway. Re-creating the map from scratch is time-consuming and error-prone.
Dynamic FAQ
Q: What protocols does the 13323-01 support? A: Primarily Modbus RTU (serial) and Modbus TCP/IP (Ethernet). Exact interface availability depends on the specific hardware revision.
Q: Does this module require an external power supply? A: No. It is powered entirely from the 3500 rack backplane.
Q: Can two gateways be used for redundancy? A: Yes. Dual 3500/92 modules are supported in redundant configurations for higher availability.
Q: Is the 13323-01 still available new? A: Availability of specific revisions varies. Functional New Surplus and refurbished units are commonly used for direct replacements.
Q: What warranty and authenticity documentation come with New Surplus or Refurbished stock? A: Units ship with functional test records, clear origin marking (New Surplus or Refurbished), firmware verification, and a standard parts-and-workmanship warranty.
