The core business of Kwant Controls is the design and manufacturing of various types of control units for the electrical remote control of practically all kinds of propulsion and steering devices, such as: traditional main engine/clutch/CPP-FPP shaft lines, tunnel thrusters, azimuthal thrusters, rudders and water jets.

  • Most units can be equipped with drive motors for automatic lever synchronization in a multi-station electric shaft/telegraph system.
  • Various machinery interfaces can be selected from e.g. potentiometer, 4-20mA, micro-switch contacts or even integrated CAN.
  • In case of remote control failure, one can rely on our traditional lamp type Engine Order Telegraphs, for signalling between Bridge, Control- and Engine Room.
  • Feedback from the vessel’s actuators can be displayed using our panel- or ceiling mounted range of indicators.
  • Customer specific control panels, with built-in lever units, signal lamps, pushbuttons, indicators, buzzers, electronic dimmers et cetera can be supplied. These panels are available with interface modules and PLC’s, together forming a Propulsion Remote Control system tailored to customer requirements, completely functional Factory tested (with or without class and/or customer in attendance).
  • For maximum flexibility of control on board, and eliminating the need for having fixed control positions, class approved portable wireless control systems can be supplied with all control devices integrated.


The RSCU-mk4 comes with potentiometers and/or micro switches for the electrical interface with the propulsion- and steering control systems. It is available with a IP42 or IP56 rating, and with the possibility to limit the speed lever travel and/or steering angle according to your requirements. Palpable stops (detents) can be supplied in both sections. It comes in top- as well as bottom mounted models, the latter for flush mounting.

The RSCU-mk4.2 has been designed for twin engine and rudder control in a single device. The speed levers can move independently, whereas rudder control is simultaneous i.e. the two rudder potentiometers move in synchronicity. Unlike the mk4, it’s rotation angle is limited to +/-60°, and it comes in flush mounted version only.

The RSCU-mk4 series are not available with stepper motors for electric shaft operation.

All executions are type-approved by ABS, BV, CCS, DNV-GL, LRS, NKK , RINA and RMRS.
