ILLUM 24VAC/DC
The DEIF Norcontrol DLQ96-PC-NB is a panel-mounted RPM meter designed for accurate shaft speed indication within marine engine control and monitoring systems. Covering a measuring range of 150-0-150 RPM with a bipolar scale, it is suited to applications where both ahead and astern rotational direction must be displayed. As a core component within the Marine Control System category, it provides bridge and engine room operators with reliable, real-time speed data essential for safe manoeuvring, propulsion management, and engine performance oversight.
Key Features
✓ Measures shaft rotational speed across a 150-0-150 RPM range, with an analogue input of 10-0-10V and an adjustment tolerance of ±10%, enabling precise calibration to the connected signal source.
✓ Load impedance rated at greater than 104Ω and illumination supply of 24VAC/DC, making it compatible with standard panel power arrangements commonly found in marine automation consoles.
✓ Designed for integration with DEIF and Norcontrol engine control panels and monitoring systems; compatibility with specific controllers or alarm systems is subject to confirmation based on the installation configuration.
✓ Panel-mount format suitable for installation in enclosed bridge consoles, engine control rooms, or local control stations; mounting cutout and environmental ratings should be confirmed against vessel-specific drawings.
✓ As a direct replacement component, it supports like-for-like substitution in existing Norcontrol installations, minimising reconfiguration requirements and reducing vessel downtime during maintenance or overhaul.
Marine Applications
✓ Main propulsion shaft speed monitoring on merchant vessels, ferries, and offshore support vessels equipped with Norcontrol or DEIF engine management systems.
✓ Bridge control consoles and integrated navigation systems where ahead/astern RPM indication is required for manoeuvring operations in port or restricted waters.
✓ Engine control rooms on bulk carriers, tankers, and container ships requiring continuous propulsion speed readout during sea passage and harbour approach.
✓ Thruster control panels on platform supply vessels, anchor handling tugs, and DP-equipped vessels where rotational feedback supports dynamic positioning operations.
✓ Retrofit and panel upgrade projects where ageing instrumentation is being replaced to maintain system integrity and operational compliance on older tonnage.
Why Marine Engineers Choose
The DEIF Norcontrol DLQ96-PC-NB is a trusted instrument recognised for its straightforward integration into existing Norcontrol panel architectures. Its clear bipolar scale, standard signal input, and 24V illumination supply align with the conventions of established marine control system designs, making it a practical choice for maintenance teams seeking reliable like-for-like replacement without extensive reconfiguration.
Ideal For
Merchant vessels, ferries, offshore support vessels, platform supply vessels, anchor handling tugs, bulk carriers, tankers, and container ships operating Norcontrol or DEIF engine control and monitoring systems.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, commissioning, and integration of this RPM meter within existing marine control systems. Services include remote diagnostic support, onboard installation guidance, bench testing, and retrofit or panel upgrade consultation — all subject to confirmation of the specific system configuration. To verify compatibility and ensure correct supply, buyers are advised to share nameplate photographs, the full part number (1113150021A), any available panel drawings or system schematics, the control system model and software version, and vessel name or IMO number where applicable. All compatibility and fitment assessments are subject to confirmation based on the information provided.
