The DEIF IMCON FC-5N is a frequency converter designed for use within marine control systems, converting AC frequency signals in the 45–55 Hz range into a 20 mA DC analogue output. This type of transducer-class signal converter plays a critical role in translating frequency-based measurements — such as generator speed or shaft rotation — into standardised current loop signals suitable for monitoring, control, and automation equipment onboard. As part of a vessel’s marine control system infrastructure, it enables accurate data transmission to indicators, controllers, and alarm panels, supporting reliable operational oversight in engine rooms and power management environments.
Key Features
✓ Converts AC frequency input (45–55 Hz) to a 20 mA DC analogue output signal, suitable for integration with standard current loop instrumentation and control systems.
✓ Supports a maximum load resistance of 750 Ω on the output circuit, with an auxiliary supply requirement of 380 V AC at 5 VA — specifications confirmed from original product data.
✓ Designed for compatibility with DEIF IMCON series marine control and monitoring systems; system-level integration with specific panels or controllers should be confirmed against installation drawings.
✓ Intended for installation in controlled onboard environments such as engine control rooms or switchboard panels; exact mounting format and enclosure rating are subject to confirmation from unit inspection or technical documentation.
✓ Serves as a direct replacement or spare component within existing DEIF IMCON installations, supporting system continuity and minimising downtime during maintenance or fault rectification.
Marine Applications
✓ Engine room control and monitoring systems requiring frequency-to-current signal conversion for generator or shaft speed measurement.
✓ Power management systems onboard commercial vessels where analogue current loop signals are used to relay rotational frequency data to centralised controllers.
✓ Auxiliary machinery monitoring panels on cargo vessels, tankers, and offshore support vessels utilising DEIF IMCON control architecture.
✓ Alarm and monitoring systems on ferries, bulk carriers, and general cargo ships where accurate analogue signal conditioning is essential for operational safety.
✓ Retrofit and upgrade projects on vessels maintaining or modernising legacy DEIF IMCON-based control system installations.
