Introduction
The model 123616-01 is a Power Supply Card for use within specific chassis of the Bently Nevada 3500 Machinery Protection System, such as the 3500/15 Relay Module or other modular power chassis. This field-replaceable card is responsible for converting the incoming DC power from the 3500 rack's main power supply into the specific voltage levels required to energize the relay coils and power the internal logic of the module. It is a critical component for ensuring that the relay outputs function correctly, enabling alarms and shutdown commands to be executed reliably.
Parameters / Specifications
The following table outlines the key technical parameters for the 123616-01 power supply card.
| Parameter | Specification |
|---|---|
| Model Number | 123616-01 |
| Description | Power Supply Card (for 3500/15 Relay Module or similar) |

| Compatibility | Bently Nevada 3500/15 Relay Module and other compatible modular chassis. |
Note: This component is an internal sub-assembly, not a standalone device. Its specifications are designed to work exclusively within its designated host module. Always verify the host module's part number and configuration before replacement.
Application Scenarios
The 123616-01 power supply card is a critical internal component used in a single, specific application scenario.
Internal Power for 3500/15 Relay Module:
Its sole primary application is to be installed inside a Bently Nevada 3500/15 Relay Module chassis. It provides the necessary power to energize the relay coils and internal logic circuits. Without a functioning power supply card, the relay module cannot execute its alarm or shutdown commands, rendering that protection channel inoperative.
Module Repair and Maintenance:
This card is used as a direct replacement part during the repair of a faulty 3500/15 Relay Module. If a module fails its diagnostics or loses output capability, this card is one of the key components replaced by repair technicians to restore the module to full functionality.
Spare Part for Critical Systems:
Plants with a high reliability requirement may keep this card as a spare part in their inventory. This allows for a faster repair turnaround for a critical relay module, minimizing the time a machine is operating with a reduced level of protection.
