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-H96 and H144 come with potentiometers and/or micro switches for the electrical interface with the propulsion- and steering control systems. The default IP-rating is IP56, 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.

Both models are available with stepper servo motors, driven by either:

  • An external Control Unit to Bus Interface module (‘CUBI’). This module is the interface to the (redundant) CAN bus, which forms the basis for the Electric Shaft system of the( fifth generation), ELAS-5. The CUBI also offers an (limited) amount of I/O for the human-machine interface i.e. signal lamps, pushbuttons and buzzers.
  • Integrated CAN electronics (I-CAN) offering a direct CAN-Open machinery interface. This option requires the presence of a CAN bus master station.
