SI-TEX SRA-1 Rudder Indicator f/Use w/SP70 80

Description

The SI-TEX SRA-1 Rudder Indicator is a dedicated analog display that shows actual rudder angle on compatible SI-TEX SP-series autopilot systems. Its backlit analog dial gives the helmsman an immediate visual reference of rudder position during manoeuvring, docking, fishing, and autopilot operation. It is designed for SP-70, SP-80, and SP-110 systems with a compatible rudder-feedback transducer and indicator output.

The SRA-1 is a display-only accessory and does not include a feedback sensor, autopilot computer, heading sensor, steering drive, or hydraulic pump. It installs in an 85 mm, or 3.3-inch, dash cutout, uses a 110 mm round bezel, and includes a mounting bracket and backlight bulb.

Key Specifications

• Analog rudder-angle indicator for compatible SI-TEX SP-70, SP-80, and SP-110 autopilot systems.
• Displays physical rudder position through a high-visibility backlit analog dial.
• Uses an approximately plus-or-minus 45-degree rudder-angle scale.
• Requires a compatible rudder-feedback transducer and processor indicator output.
• Operates from 12V DC supplied through the compatible autopilot system.
• Installs in an 85 mm, or 3.3-inch, dash or console cutout with a 110 mm round bezel.
• Uses a UV-stabilized ABS housing with IP56 front-panel protection.
• Includes a mounting bracket and backlight bulb and weighs approximately 0.4 kg.

System Integration

The SRA-1 does not control the autopilot and cannot create rudder-angle data by itself. It displays the physical position signal supplied by a compatible rudder-feedback transducer and SI-TEX processor. Confirm that the installed SP-series autopilot provides the appropriate indicator output and that the feedback sensor supports the planned display arrangement.

Additional indicators can be useful on vessels with multiple operating positions, such as an enclosed helm and aft work station. Verify the permitted number of connected displays, cable-run length, voltage supply, and processor-output configuration before adding more than one indicator.

Installation Considerations

Select a dash or console location with clear visibility, sufficient 85 mm cutout space, 110 mm bezel clearance, rear wiring access, and protection consistent with its IP56 front-panel rating. Secure the mounting bracket, connect the indicator to the compatible processor output, and verify port, amidships, and starboard indication after rudder-feedback calibration.

Before Ordering

Confirm a compatible SI-TEX SP-70, SP-80, or SP-110 autopilot system, installed compatible rudder-feedback transducer, available indicator output, 12V supply, 85 mm panel cutout, 110 mm bezel clearance, rear wiring access, suitable viewing location, and required number of indicator displays before purchase.
