Designed for signaling cabinets – Stable operation in control rooms and wayside enclosures, typically on 24 VDC supply.
Legacy-friendly serial connectivity – Commonly supports RS‑232/RS‑485 for interlocking and SCADA integrations.
Variant alignment – N897163510Q, N897163050Q, and N897163100U align with project-specific builds, easing one-for-one replacement.
Serviceability in the field – Front-access connectors and status LEDs in most builds make commissioning and fault tracing faster.
Robust EMC behavior – Built for electrically noisy sites; typically paired with shielded cabling and surge protection.
Stable, deterministic links – Suits low-bandwidth but safety-relevant traffic where consistency matters more than peak throughput.
| Brand / Model | ALSTOM – N897163510Q / N897163050Q / N897163100U (industrial modem module) |
| HS Code | 8517.62.00 (Data transmission equipment) |
| Power Requirements | 24 VDC nominal; wide-range DC inputs are common (often 18–36 VDC in many builds) |
| Operating Temperature | Typically −25 °C to +70 °C for wayside/control room environments |
| Signal Input/Output Types | Serial interfaces commonly RS‑232 and/or RS‑485; status LEDs and service port depending on variant |
| Communication Interfaces | Point‑to‑point or multi‑drop serial modem operation; some cabinets include an associated Ethernet bridge |
| Installation Method | DIN‑rail or panel mounting inside protected control cabinets; front-access connectors are typical |
| Dimensions & Weight | Compact module form factor (approx. 120 × 100 × 35 mm; ~0.4 kg, varies by variant) |
Signaling interlockings and control cabinets (wayside and central rooms)
Remote I/O backhaul for trackside equipment (point machines, signals, TPWS/ATP)
Depot and station SCADA data links (alarms, metering, environment monitoring)
Condition-based maintenance links for legacy subsystems where Ethernet isn’t native
Low-risk replacement – Direct fit for existing ALSTOM-built panels, reducing retesting and requalification effort.
Compatibility first – Keeps serial protocols and wiring intact, which typically avoids interface converters.
Reduced downtime – Pre-tested units help maintenance teams turn repairs quickly during night possessions.
Lifecycle support – We help match the exact variant (e.g., N897163510Q vs N897163100U) by cabinet BOM and photos.
Cost control – Extends asset life without wholesale migration to new network architecture.
Cabinet environment: Install in a sealed control cabinet with adequate ventilation; keep ambient within specified range.
Power & grounding: 24 VDC supply with correct polarity; bond shields at one end; implement cabinet earth per site standard.
Wiring: Use shielded twisted pairs for serial/line connections; maintain separation from power cables to minimize noise.
Surge protection: In most cases a series surge arrester on field lines is recommended for lightning-prone routes.
Commissioning: Record DIP/parameter settings; verify link using loopback or built‑in test LEDs before handover.
Routine maintenance: Quarterly connector inspection and dust cleaning; annual link test; keep a backup of parameters/firmware where applicable.
Spares practice: Many teams keep 10–15% spares on critical corridors; seems to reduce mean time to restore significantly.
CE compliance and RoHS alignment typical for control-cabinet electronics
EMC for railway installations often aligned to EN 50121 series (project dependent)
Manufacturing quality systems generally aligned with ISO 9001
Manufacturer’s warranty support: 12 months
24 VDC DIN‑rail power supply (industrial grade, with brown‑out ride‑through)
Surge protectors for line and serial ports (railway-rated, fast clamping)
Shielded serial cables (RS‑232/RS‑485) with proper pinout per cabinet drawing
DIN‑rail Ethernet switch (if bridging to IP networks is required in the cabinet)
From a recent depot team: “Swapping the N897163050Q was straightforward—same connectors and settings as the old unit. Link came up on first power, so we finished within the blockade.” That’s typically what we aim for: predictable behavior and minimal rework.
