NABCO MRS-L 430366 Product Description

Overview

NABCO MRS-L 430366 is recorded as a Nabco voltage sensing relay for industrial automation or marine remote-control systems. Public Ram Automations records identify the MRS-L as a volt sense relay associated with Nabco Omron Nippon Air Brake Co. Ltd., operating from a DC 24 V power source. The supplied number 430366 likely serves as a part, tag, board or order reference; no public official Nabco datasheet was located for that exact number, so electrical ratings and terminal function should be verified from the relay label, wiring diagram or original equipment manual.

Features

The MRS-L relay is described as a voltage sensing relay used in remote control or industrial automation applications. The public distributor record lists DC24 V compatibility, voltage sensing range 1.0 to 3.0 volts and unit weight 290 g. The record also identifies an associated part number PM-GE COMI.5508.642/E010030200, which may be the relay, PCB or replacement assembly reference rather than the supplied 430366 code.

No confirmed public datasheet was located for contact arrangement, contact current rating, contact voltage, coil resistance, pickup or drop-out voltage, delay time, terminal layout, mounting type, dimensions, protection rating, fuse rating, compatible controller, isolation or communication interface. These fields must not be assumed. In marine or engine-control installations, the relay may monitor a control voltage, status signal, interlock loop or alarm circuit, but the exact function must be checked against the Nabco system diagram.

Principle

A voltage sensing relay monitors a control voltage or analog status signal and switches its internal contacts when the measured voltage crosses a preset threshold or enters a defined range. In a remote-control or marine engine-control system, this type of relay may provide interlock, status confirmation, alarm triggering, supply-fault detection or control-circuit enablement. The DC 24 V relay coil or sensing supply is distinct from the 1.0 to 3.0 V sensing range listed in the public record, so the terminal circuit should be confirmed before wiring.

Replacement should verify the model MRS-L, reference 430366, associated part number, DC supply polarity, sensing input terminals, contact NO or NC arrangement, contact load, wiring numbering, relay base or socket, mounting space, threshold setting, delay function and PLC or alarm panel connection. If the relay belongs to a ship main-engine control, safety interlock, steering, propulsion, alarm or emergency shutdown circuit, replacement must follow qualified marine engineering procedures, system isolation, lockout, tagout and Nabco documentation.

Applications

NABCO MRS-L 430366 is associated with existing Nabco remote-control, engine-control, marine automation, alarm or interlock panels where a DC voltage status signal requires relay conversion or threshold monitoring. It may serve as a maintenance spare in propulsion control panels, generator control panels, pump or valve control skids, shipboard automation cabinets and industrial control assemblies, but direct interchange should be confirmed by matching the rating plate, socket, wiring diagram and original spare-parts list.
