Product Overview

• Brand: DEIF A/S (a global provider of power control, monitoring, and automation solutions)
• Model: 11-0018905
• Type: Power Management System (PMS) Communication Module / I/O Expansion Card
• Industry: Marine (merchant ships, offshore vessels), power generation (diesel gensets, renewable energy), industrial backup power, and microgrids.
• Function: Acts as a communication interface or I/O expansion module for DEIF’s Power Management Systems (e.g., DEIF PMS 300, PMS 400) and genset controllers (e.g., DEIF DGC-2020). It enables data exchange between DEIF’s central controllers and peripheral devices (e.g., gensets, circuit breakers, sensors) via standard industrial protocols. Additionally, it expands the controller’s I/O capacity to monitor and control more field devices, ensuring seamless coordination in power distribution networks.

Key Features

1. Multi-Protocol Communication Support
   • Integrates standard industrial communication protocols to enable interoperability with DEIF and third-party systems:
     • Modbus RTU/TCP: For communication with genset controllers, circuit breakers, and SCADA systems.
     • CANopen: For reliable, real-time data exchange in harsh industrial/marine environments (resistant to vibration and electrical interference).
     • DEIF Proprietary Protocols: Optimized for communication with DEIF’s PMS and genset controllers (e.g., DEIF DNP3 for power system data logging).
   • Supports dual Ethernet ports for network redundancy, ensuring uninterrupted communication even if one network path fails.
2. I/O Expansion Capability
   • Expands the host controller’s input/output capacity with a mix of analog and digital channels (estimated based on DEIF’s similar modules):
     • Analog Inputs (AI): 4–8 channels (4-20 mA / 0-10V) for monitoring parameters like genset load, voltage, or fuel level.
     • Digital Inputs (DI): 8–16 channels (24V DC) for status signals (e.g., circuit breaker position, genset running/stopped).
     • Digital Outputs (DO): 4–8 channels (relay contacts or open-collector) for controlling devices (e.g., starting gensets, triggering alarms).
   • Channel-to-channel galvanic isolation (500V AC) prevents ground loops and EMI/RFI interference, critical for signal integrity in power systems.
3. Marine-Grade Reliability
   • Constructed to meet marine industry standards, making it suitable for offshore and shipboard applications:
     • Compliant with IEC 60945 (marine navigation and radio communication equipment) and DNV GL, ABS, or LR certifications (common for marine electronics).
     • Resistant to harsh environmental conditions: salt spray, high humidity, vibration (IEC 60068-2-6), and shock (IEC 60068-2-27).
4. Plug-and-Play Integration
   • Designed for seamless integration with DEIF’s PMS and genset controllers. It is automatically detected by DEIF’s configuration software (e.g., DEIF PC-Tool), eliminating the need for complex manual programming.
   • Hot-swappable capability (inferred from DEIF’s modular design standards) allows module replacement without shutting down the entire power management system, minimizing downtime for critical power networks.

Applications

• Marine Power Management:
  • Enables communication between DEIF’s PMS and shipboard gensets, switchboards, and thruster systems. Ensures load sharing, genset synchronization, and blackout prevention on merchant ships, offshore supply vessels (OSVs), and drilling rigs.
  • Expands I/O capacity to monitor fuel levels, cooling water temperature, and exhaust gas temperature (EGT) of marine gensets.
• Industrial Backup Power:
  • Integrates with DEIF-controlled diesel gensets in data centers, hospitals, or manufacturing plants to monitor genset status and control automatic transfer switches (ATS).
• Renewable Energy Microgrids:
  • Facilitates communication between DEIF’s controllers and solar inverters, wind turbines, or battery energy storage systems (BESS). Helps balance power supply and demand in hybrid microgrids.

   • Configure via DEIF’s PC-Tool software to select communication protocols, map I/O channels to field devices, and set alarm thresholds.
2. Wiring Guidelines:
   • Use shielded cables for analog and communication signals to minimize EMI interference from nearby power cables (common in engine rooms).
   • Ensure proper grounding of the module’s chassis to the control cabinet ground, complying with marine or industrial electrical codes.
3. Safety & Troubleshooting:
   • Follow lockout-tagout (LOTO) procedures when wiring or servicing the module in live power systems to avoid electrical shock.
   • Use LED indicators to diagnose issues:
     • Green LED: Normal operation (power and communication active).
     • Red LED: Communication fault or module error.
     • Amber LED: I/O channel fault (e.g., open-circuit sensor).
   • For communication failures, verify network settings (IP address, baud rate) and check cable continuity. For I/O issues, use a multimeter to test sensor/actuator signals.

Critical Notes

1. Model Specificity: The part number 11-0018905 may correspond to a specific configuration (e.g., protocol support, I/O count). Confirm exact specifications with DEIF, as variants may exist for marine vs. industrial applications.
2. Protocol Licensing: Some advanced protocols (e.g., Profinet) may require a separate license from DEIF. Verify protocol availability before integrating with third-party systems.
3. Genuine Parts Recommendation: For marine safety and power system reliability, use genuine DEIF modules. Aftermarket alternatives may not meet marine certifications (e.g., DNV GL) or DEIF’s communication protocol standards, risking system instability.
