RSA-series, Rudder angle

Indicators of the RSA-series have been especially designed for rudder angle indication. Types RSA-3 thru RSA-7 are based on the same servomotor principle (RSM-4) and require only an external potentiometer as well as a 24VDC supply voltage to make them operational. The RSA-9 and RSA-10 are cost reduced versions of the RSA-7 and RSA-4 respectively.

Kwant Controls also supplies a matching signal transmitter mounted in a rugged housing, the RSG.-1 which can be linked to the rudder machine by means of a sprocket and chain connection. A combination of the RSG-1 and one (or more) of the RSA indicators together form a reliable rudder angle indication system that will last for many years without any maintenance. Diagrams have been added to show some of the possible system set-up’s. In case a panel indicator with a 4-20mA signal input is required, an indicator of the ISI family should be used. These indicators offer galvanic isolation of the input signal and power supply. Please refer to the ISI datasheet for further information.

ISI-series, general purpose

The general purpose indicators of the ISI (Isolated Signal Indicators) series have been designed for various applications and offer the advantage of galvanic separation of the input signal and the supply voltage, thus preventing ground loop problems. The series is based on the DC servomotor principle and require an external 4-20mA signal source as well as a 24VDC supply voltage. The 24VDC LED dial illumination can be dimmed externally.

LBM-series, bargraph

The Kwant Controls bar graph indicators of the LBM series are equipped with 41 light emitting diodes (LED’s) in either green, red or yellow, therefore the display resolution is 2,5%. They can be dimmed by means of an external low cost potentiometer, and have dial illumination in matching colours. The housing is made of black anodized aluminium, while the electronic circuitry has been sealed with a hardening compound to ensure trouble free operation. The reading can be adjusted by means of two trimmer potentiometers located at the back of the unit. The LBM-4 and 5 are available in horizontal or vertical orientation.

RSCU mk4

The RSCU-mk4 series consist of two members in the following executions:
  • RSCU-mk4 (96x96mm);
  • RSCU-mk4.2 (96x96mm)
They both share the classic recognisable bow-shaped rotatable top section. The control units of the RSCU series (Rotation and Speed Control Unit) are console mounted lever units designed for controlling both speed (RPM or pitch) and heading (azimuth). All types can be equipped with potentiometers and/or micro switches for both speed as well as heading control. The motorized executions are all stepper motor driven and linked by means of CAN bus for automatic synchronization (Electric Shaft) with remote stations or an external master system.

PMA-1 & 2

The PMA-1 is the basic angle controller that allows for driving any angle transmitter, usually a potentiometer. Main applications are rudder- and transverse thruster control. The PMA-2 is a PMA-1 with the spring return to zero feature.

ASA-series, 360°

Indicators of the ASA-series have been designed for 360° endless thruster azimuth angle indication. They are based on the servomotor principle and require only an external potentiometer as well as a 24VDC supply voltage to make them operational. The essential difference when compared to standard indicators, is that the ASA’s pointer(s) can rotate endlessly without an end stop. To achieve this, a twin wiper potentiometer must be used as angle transmitter.
