10 Drive Units RPU80, RPU160 and RPU300 REVERSIBLE PUMP Hydraulic steering systems are now being used in every category of vessel. In many respects hydraulic steering is preferable to mechanical steering. Hydraulic systems normally comprise of two main components, a steering wheel pump and steering cylinder(s). The steering wheel pump may be either a gear pump or a plunger pump. Which ever type is installed, steering is achieved by turning the steering wheel in either direction causing oil from the wheel pump to be supplied to the appropriate side of the cylinder. Oil is returned via the opposite side of the cylinder back to the pump. The linear motion of the cylinder rod is transformed to a rotary motion by the tiller, which turns the rudder shaft and rudder. Check valves (non-return valves) are usually incorporated to prevent the rudder driving the steering wheel pump. If an autopilot is to be included in such a hydraulic steering system, then the oil flow providing the rudder movement must be controlled by electrical signals from the autopilot. The maximum flow rate of RPU80, RPU160 and RPU300 is 0,8 l/min., 1,6 l/min. and 3,0 l/min. respectively, measured at a pressure of 10 bar with nominal voltage (12 VDC) on the motor terminals.

RPU80 Rpu160 reversible pump Part Number Description 21118203 RPU-160: Reversible Pump for cylinder size 160 - 400 cu.cm. (9,8 – 24,4 cu.in.) RPU160 Rpu300 reversible pump Part Number Description 21118211 RPU300-12 V: Reversible Pump. For cylinder size 320 – 740 cu.cm. (19,5 – 45,2 cu.in.) 21118476 RPU300-24 V DC: Reversible Pump. For cylinder size 320 – 740 cu.cm. (19,5 – 45,2 cu.in.) Rudder Feedback Units RPU300 RF14XU RUDDER FEEDBACK UNIT The rudder feedback unit transmits a signal proportional to the rudder angle. It is mounted close to the rudder stock and is mechanically connected to the rudder by a transmission link in a 1:1 ratio. The RF14XU Rudder Feedback Unit consists of a glass reinforced non-flammable polyester housing with a mounting plate of sea-water resistant aluminium. It contains a potentiometer, limit switches and an electronic drive module. Output is either a voltage varying ±9 volts around half the supply voltage, or a frequency signal with 3400 RF14XU Hz for use with a Simrad autopilot. The shaft of the Feedback Unit is free to travel 360 degrees, but only ±90 degrees from midposition are used for signal control. RF14XU is equipped with two sets of micro switches, which can be used as electrical limit switches for the steering gear.

RF45X RUDDER FEEDBACK UNIT The RF45X is a medium duty rudder feedback unit. It is a repairable rather than a potted “throw away” item. The RF45X has “universal” frequency output which can be used with both AP35 and AP50, and the older AP45 and AP9 without the use of internal jumpers. 11 Part Number Description 22011415 RF45X Rugged rudder Feedback Unit; with transmission link and 2m Cable. RF45X RF300 Rudder Feedback The RF300 is a medium duty rudder feedback unit which connects directly to the Autopilot Pilot Computer using 2 wire frequency interface. Part Number Description 20193744 RF300 Rudder Feedback Unit: with transmission link and 10m Cable. RF300 Rudder Feedback Heading Sensors CD100A course detector Magnetic compass course detector to be mounted under the boats own compass. Used together with CD135. Part Number Description 20106688 CD100A Course Detector; with 5m. Cable. Magnetic course detector with tripod holder for overhead and for conventional magnetic compass. CDI35 dedicated magnetic compass interface unit The CDI35 is used with CD100A only. It converts the Sine/cosine signal from CD100A into a two-wire pwm signal, similar to the RFC35 Compass. Also used with AP35. Part Number Description 22087001 CDI35 Course detector interface. Interface unit to connect autopilot to magnetic compass with CD100A or CD109 course detector. RC25 rate compass The Simrad RC25 Rate Compass is used with AP35 and AP50 (Robnet). Fluxgate compass with integrated rate of turn sensor. Utilizes a solid state rate sensor and a magnetic fluxgate sensor. Provides a dramatic improvement to the dynamic performance of both the autopilot and a stabilized radar display. Part Number Description 22084438 RC25 Rate compass; High performance fluxgate compass with integrated rate gyro provides more stable heading, with 15 m cable RC25 RFC35 fluxgate compass Simrad RFC35 Fluxgate Compass can be used with AP35 and AP50 (Two wire pwm) Part Number Description 22086995 RFC35 Electronic fluxgate compass; with 15 m cable RFC35 Professional Series Autopilot, Gyro Compass and Heading Sensor Solutions
