The Praxis Automation Technology 98.6.032.702 is a high-reliability input/output module specifically engineered for the Mega-Guard series of marine automation and navigation systems. This module functions as a versatile node within a distributed control network, facilitating the monitoring and control of essential shipboard machinery and electrical systems.

 

Product Overview

As a core component of Praxis marine electronics, the 98.6.032.702 module is designed for longevity and precision in maritime environments. It features a robust hardware architecture that supports both digital and analog signals, allowing it to interface with sensors, switches, and actuators across the vessel. The module communicates via a redundant fieldbus network, ensuring that critical data for propulsion, power management, and cargo handling remains available even in the event of a single network fault.

Application Fields

• Integrated Monitoring and Control System (IMCS): Serving as a data acquisition point for ship-wide alarms and status monitoring.
• Power Management Systems (PMS): Managing diesel generator sets, circuit breakers, and load sharing operations.
• Extension Alarm Systems: Relaying critical engine room alarms to the bridge and engineer cabins.
• Propulsion Control: Interfacing with bridge levers and engine governors to manage vessel speed and direction.

 

Product Instructions

• Installation: Mount the module on a standard TS35 DIN rail inside a ventilated control cabinet. Ensure the mounting position avoids direct exposure to high-heat sources.
• Bus Termination: When the module is located at the physical end of a CAN-bus segment, ensure the internal or external 120-ohm termination resistor is correctly engaged.
• Address Setting: Configure the unique hardware ID (node address) using the onboard rotary switches or through the Praxis configuration software prior to system startup.
• Wiring: Use standardized industrial connectors for I/O wiring. The Praxis 98.6.032.702 requires shielded cabling for all communication lines to ensure compliance with marine EMC standards.

 

Q&A: Frequently Asked Questions

• Q: Can this module be used in open-deck installations?
  • A: No, the 98.6.032.702 has an IP20 rating and must be installed within a secondary IP-rated enclosure (typically IP44 or higher for marine use).
• Q: Does the module support “Safe State” outputs?
  • A: Yes, in the event of a communication loss, the digital outputs can be programmed to either hold their last state or default to a pre-defined safety position (Open or Closed).
• Q: What is the significance of the “Status” LED color?
  • A: Green indicates normal operation and active heartbeat; Red indicates a hardware failure or internal error; Flashing Orange indicates a configuration mismatch or address conflict.
• Q: Is it compatible with other manufacturer’s PLC systems?
  • A: While designed for Praxis Mega-Guard systems, the module uses standard protocols. However, full functionality and diagnostics are optimized for Praxis central processing units.
