Product Introduction & Supply Chain Strategy
The Praxis Automation 98.6.034.802 is a specialized PMS I/O module engineered for Praxis Mega-Guard marine automation and power generation control platforms. Installed directly inside shipboard switchboards and control cabinets, this module monitors voltage, frequency, and current parameters across main generators, facilitating automatic synchronization, load-dependent start/stop sequences, and preferential trip execution.
Maintaining the 98.6.034.802 as New Surplus is a vital risk-mitigation strategy for fleet managers, marine engineers, and port superintendents. A malfunction in a PMS I/O module can prevent generator paralleling or trigger un-commanded busbar trips, risking total vessel blackout while underway or maneuvering in port. Sourcing genuine, unused OEM surplus ensures immediate swap-ability and compliance with marine class standards without suffering long factory backorders or risking the installation of moisture-damaged, secondhand salvage parts.
Installation & Configuration Guide
1.Pre-Installation (Prep & Safety):Switchboard LOTO, vessel safety, and ESD protection.
Coordinate with the Chief Engineer to transfer load to a backup generator or shore power. Isolate 24 VDC control power and high-voltage sense lines to the target switchboard cabinet using strict marine lock-out/tag-out (LOTO) procedures. Strap on a grounded ESD wrist band before opening control enclosures.
2.Removal:Unplugging fieldbus connectors and rail dismount.
Label and disconnect all terminal blocks, fieldbus cables, and power wiring leads connected to the module faceplate. Release the spring-loaded DIN-rail latch on the bottom or top of the housing and carefully remove the failing 98.6.034.802 module from the DIN rail.
3.Installation (Clone & Seat):DIP switch/node address setting and mounting.
Unpack the new 98.6.034.802 module from its protective anti-static bag. Check that all address DIP switches or system identification jumpers on the replacement unit match the original module settings exactly. Snap the module securely onto the cabinet DIN rail, then reattach all labeled terminal plugs and fieldbus cables.
4.Power-On & Testing:24 VDC power check, bus link, and generator test.
Restore 24 VDC control power and observe the onboard diagnostic LEDs (Power, Bus Run, Fault). Access the Mega-Guard central operator station to confirm node communication. Perform a controlled generator start and manual/auto synchronization test to verify proper load-sharing and I/O feedback.

Firmware/Software Versions & Upgrade Notes
- System Addressing: Ensure the hardware node address DIP switch array on the 98.6.034.802 matches the original module configuration prior to applying power; incorrect addressing will cause CAN-bus network collisions.
- Redundant Power Input: Marine PMS cabinets typically feed dual redundant 24 VDC supplies to this module. Ensure both primary and secondary DC power feeds are verified before releasing the system for automated operation.
- Vibration and Grounding: Check that cabinet DIN-rail grounding clips are clean and free of corrosion to ensure low-impedance grounding against hull structure electrical noise.
Frequently Asked Questions (FAQ)
This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.
Why choose New Surplus over a refurbished or salvaged Praxis module?
Marine electronics are subjected to constant hull vibration, ambient humidity, and thermal stress inside engine room switchboards. Refurbished or vessel-salvaged modules often harbor corroded PCB traces, degraded optocouplers, or moisture damage that leads to intermittent PMS network dropouts. Our New Surplus 98.6.034.802 modules are unused factory original units, delivering full component integrity and long-term operating reliability.
How is the physical and functional condition of the 98.6.034.802 verified?
Our technical team conducts multi-point inbound inspections. We inspect the housing plastics, verify un-marred DIN-rail mounting latches, confirm pristine gold connector contacts, and ensure the module is preserved in static-shielded packaging.
Does this module carry marine class type approvals?
Yes. Praxis Mega-Guard components are engineered and certified to meet major international marine classification society standards (DNV, ABS, LR, BV) for installation aboard commercial vessels and offshore rigs.
Is the Praxis 98.6.034.802 interchangeable with Terasaki part numbers?
Yes. In many vessel switchboard implementations, Praxis Automation hardware is cross-referenced under Terasaki part numbers (such as 93.0.962.1). Matching the core Praxis number 98.6.034.802 guarantees direct hardware pinout and functional compatibility.
What warranty is provided with this New Surplus marine module?
We support this New Surplus Praxis Automation 98.6.034.802 PMS I/O module with a full 1-year replacement warranty. If any functional or electrical defect arises under normal operating conditions within 12 months, we replace the component directly from our available stock.
