Detailed description
Detailed description
The SIMRAD AD80 analog control card is a key component for marine autopilot systems. Designed for integration with Simrad AP70 and AP80 autopilot systems, as well as Simrad Pro configurations with the AC85 computer, it provides precise analog or proportional control of a vessel’s rudder or thruster.
Advanced control and feedback
The AD80 enables control via analog voltage or low-level current for angular and proportional steering. It supports multiple feedback types, including frequency, voltage, or current for angle feedback. This versatility ensures compatibility with various steering configurations and precise heading management.
Connectivity and interfaces
This card features outputs such as « UI CRTL » for low-voltage analog current commands and « READY » for a contact signal indicating its operational status. Inputs include « RUD UI » for analog rudder feedback (voltage or current), « RUD FRQ » for rudder feedback via frequency, and « MODE » for an external mode selector. Generic link establishment signals « HS1 » and « HS2 » are also present. Connection to the network is via SIMNET for the CAN network, and an isolated 4-20mA analog output is available. The system uses a Micro-C CAN bus for integration, requiring Micro-C cables and terminations.
Design and performance
Mounted in a bulkhead, the SIMRAD AD80 analog control card is built to withstand marine environments. It operates within a temperature range of -15°C to +55°C and can be stored from -30°C to +70°C. Weighing approximately 0.5 kg, it includes an NMEA 2000 load equivalence number (LEN) of 2. The AD80 is recognized for its ability to maintain precise heading and provide smooth, accurate steering, converting autopilot commands into stable analog signals for rudder or thruster heading control.
