Yokogawa ALP111‑S00 PROFIBUS-DP Communication Module, 12Mbps High-Speed Isolated D-Sub Interface Card for CENTUM VP FCS Node Units

Yokogawa ALP111‑S00 High-Speed PROFIBUS-DP Isolated Communication Module for CENTUM VP FCS Network Integration

1. PROFIBUS‑DP High‑Speed Bus Architecture

Yokogawa ALP111‑S00 is a dedicated DP‑V0 compliant PROFIBUS‑DP communication module built for CENTUM VP field control stations. It supports full auto‑negotiation transmission speed ranging from 9.6kbps up to 12Mbps, adapting to various field bus bandwidth requirements for different industrial control segments. The EIA‑RS‑485 compliant physical interface ensures standard, universal bus compatibility with third‑party PROFIBUS field devices, including drives, remote I/O and smart sensors.

The module provides robust data processing capacity with up to 1000 words of I/O data volume and 200 communication definitions per unit, supporting large‑scale bus node data interaction without packet loss or transmission delay.

2. Dual D‑Sub Port Design for Communication & Maintenance

ALP111‑S00 features dual independent D‑sub 9‑pin interfaces for differentiated functions. A female D‑sub port serves as the main PROFIBUS‑DP bus communication interface for regular field network data exchange. A male D‑sub RS‑232C port is reserved for on‑site equipment debugging, parameter configuration and routine maintenance. This dual‑port separation avoids maintenance operation interference with production bus communication, improving system operational safety and engineering convenience.

Compact standardized port layout simplifies field wiring and network debugging, enabling fast bus topology setup and efficient daily fault diagnosis for distributed control systems.

3. 1500V AC Isolation & Industrial Anti‑Interference Performance

Built with 1500V AC one‑minute dielectric withstand isolation between field bus circuits and internal system circuits, ALP111‑S00 effectively blocks field surge voltage, ground loop potential difference and electromagnetic interference. The isolated barrier prevents external electrical anomalies from invading FCS core circuits, avoiding system communication crash or data distortion caused by harsh on‑site conditions.

Fully compliant with industrial EMC standards, the module resists radiation noise, static discharge and power fluctuation interference. It maintains stable long‑term bus communication quality and low bit error rate in complex electromagnetic industrial environments.

4. Native FCS Hardware & Environmental Adaptability

The module is specially designed for Yokogawa FCS node units, perfectly compatible with AFV30, AFV40, ANB10/11 and ANR10 series hardware racks. It supports direct rack mounting with standardized mechanical dimensions and accurate bus docking, enabling plug‑and‑play deployment without structural modification or firmware adjustment.

It operates stably within a wide industrial temperature range of 0°C to +60°C, adapting to long‑term indoor cabinet continuous operation. Low power consumption of 0.7A @5V DC minimizes heat accumulation, while lightweight 0.3kg compact structure reduces rack load and supports 24/7 unattended industrial operation.

5. Application Scenarios & Core Competitive Advantages

Application Scenarios: Widely used in petrochemical, power and process manufacturing industries for CENTUM VP system PROFIBUS‑DP network expansion. Ideal for connecting variable frequency drives, remote I/O stations and intelligent field instruments, supporting distributed bus control, interlock data transmission and field network unified management.
