Product Introduction
ALSTOM N897164624A is an ALSTOM control module referenced in spare-part channels as a PLC controller and control board for rail and industrial automation systems. It is typically installed as a rack-mounted or cabinet-mounted board inside ALSTOM rolling stock, signaling, power, or process control cabinets.
The module is used for logic control, subsystem coordination, status monitoring, and fault handling within an ALSTOM control platform. Some third-party listings describe it as a PLC controller with MODBUS, DF1 Slave, or CANopen communication support; however, those protocol details are not confirmed by official ALSTOM documentation and should not be used as the sole basis for replacement. Other reseller pages attach unrelated industrial PC specifications to this part number, which should also be treated with caution. Always verify the installed nameplate, revision code, slot position, and cabinet drawing before procurement.
Key Technical Specifications

Quality Control Process
- Visual and code check: Confirm N897164624A part number, revision code, labeling, and connector condition.
- Nameplate verification: Confirm function label, supply voltage, firmware/revision, and compatible ALSTOM platform.
- Backplane interface check: Inspect board connectors, pin condition, and slot compatibility.
- Functional check: Verify power-up, status indicators, control response, and diagnostic behavior where test fixtures allow.
- Final packing: Record test results, apply asset labels, and ship with connector and PCB protection.
Replacement Pitfall Guide
❗ Confirm the exact revision code. N897164624A may have multiple build variants.
❗ Verify function label. Some sources call it a PLC controller; others describe it as a general control module. The nameplate and cabinet drawing should take priority.
❗ Do not treat it as a generic industrial PC or motion controller. Unverified listings may attach unrelated PC or interface specs to this part number.
❗ Check slot position and backplane type. The board must match the existing cabinet slot and connector layout.
❗ Ignore unconfirmed protocol claims. MODBUS, DF1 Slave, and CANopen support appear in third-party descriptions but are not confirmed by official ALSTOM documentation.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| ALSTOM | Same N897164624A revision | Direct | Like-for-like when revision, firmware, connectors, slot, and cabinet match. |
| ALSTOM | Other ALSTOM control/PLC module | Needs Adaptation | Confirm function label, backplane type, I/O mapping, and host system. |
| ALSTOM | Non-ALSTOM PLC controller | Not Recommended | Backplane, protocol, and configuration are typically incompatible. |
| ALSTOM | Modern ALSTOM control module | Needs Adaptation | Requires system review, firmware loading, and commissioning support. |
- Typical use: ALSTOM rolling stock cabinets, signaling and wayside control racks, power plant auxiliary systems, industrial process control, depot maintenance, and legacy system lifecycle support.
- Key verification points: N897164624A revision, function label, supply voltage, backplane connector type, installed cabinet model, slot position, and host system interface.
