TYPE: DLQ 192-BC-NB
RPM METER
0 TO 120 MIN-1 RPM ASTERN / AHEAD
INPUT: 10-0-10V
LOAD: > 10K OHM
ORDER NO: 246064.50
The DEIF NABCO DLQ 192-BC-NB is a precision RPM meter designed for marine engine speed indication, covering a measurement range of 0 to 120 min-1 in both ahead and astern directions. Operating on a 10-0-10V analogue input signal with a minimum load impedance greater than 10K Ohm, this instrument integrates into marine control systems where accurate shaft or engine speed readout is essential for safe vessel manoeuvring and propulsion management. As a component within the Marine Control System category, it provides operators and engineers with real-time rotational speed data critical to bridge and engine room operations.
Key Features
✓ Bidirectional RPM indication covering 0 to 120 min-1 astern and ahead, suitable for slow-speed and manoeuvring operations.
✓ Analogue voltage input of 10-0-10V with a load impedance requirement of greater than 10K Ohm, as specified by the manufacturer.
✓ Compatible with DEIF and NABCO marine control and telegraph systems, subject to confirmation against specific panel or controller configuration.
✓ Designed for panel-mount installation in engine control rooms or bridge consoles; exact mounting dimensions and environmental ratings should be confirmed from nameplate or technical drawings.
✓ Direct replacement reference Order No. 246064.50 supports like-for-like swap during scheduled maintenance or instrument failure, minimising vessel downtime.
Marine Applications
✓ Engine control rooms on merchant vessels requiring continuous shaft or engine RPM monitoring during manoeuvring and transit.
✓ Bridge telegraph and propulsion control consoles where ahead/astern speed indication is displayed to the officer on watch.
✓ Integrated propulsion control systems on ferries, RoRo vessels, and general cargo ships where low-speed RPM accuracy is operationally critical.
✓ Retrofit and replacement installations in existing DEIF or NABCO control panels where the original instrument has degraded or failed.
✓ Offshore support vessels and tugs where precise bidirectional RPM readout supports dynamic positioning and close-quarters manoeuvring.
Why Marine Engineers Choose
The DLQ 192-BC-NB is a purpose-built marine RPM indicator from DEIF and NABCO, combining a straightforward analogue voltage interface with bidirectional display capability. Its direct-replacement order reference and known electrical specification make it a reliable choice for maintenance teams sourcing instruments for existing control system panels without modification.
Ideal For
Merchant vessels, ferries, RoRo ships, offshore support vessels, tugs, and any commercial vessel operating DEIF or NABCO marine control and propulsion monitoring systems requiring bidirectional RPM instrumentation.
Technical Support & Compliance
Technical assistance is available to support remote troubleshooting, onboard diagnostics, installation guidance, and commissioning of this RPM meter within existing control system configurations. Retrofit and integration support can be arranged subject to confirmation of the surrounding system architecture. To verify compatibility and confirm this instrument suits your application, buyers are encouraged to share nameplate photographs, the original part or order number, panel or system model and software version, relevant wiring diagrams or drawings, and vessel name or IMO number where applicable. All compatibility and fitment assessments are subject to confirmation based on documentation provided.
