Description
⚓ Product Overview
The DEIF BW144, part number 401010056.20, is a marine Bridge Wing Rudder Angle Indicator designed to provide clear visual indication of vessel rudder position.
The BW144 is designed for bridge-wing and tiller-compartment installation. It uses an analog indication format and is based on the DEIF XL indicator design, with a pivoting mounting arrangement, rear housing, and integrated dimmer for marine installation.
With a 24 V DC supply, ±10 V input, and ±45° indication range, the BW144 can be integrated into compatible ship steering and rudder feedback systems. An amplifier such as the TDG 210-DG is specified for the BW144 configuration.

🧭 Marine Application
The BW144 is intended for applications where the helmsman or bridge personnel need a direct visual indication of rudder position.
Typical applications include:
- ⚓ Ship bridge wing steering stations
- 🚢 Tiller compartments
- 🛳️ Marine steering gear systems
- 🧭 Rudder position monitoring
- ⚙️ Steering gear feedback systems
- 🔧 Vessel automation maintenance
- 🔄 Replacement of existing DEIF/Data rudder indicators
The BW144 is specifically designed for flexible mounting and can be used in bridge-wing or tiller-compartment installations.
🔌 Electrical & System Integration
The BW144 accepts a ±10 V input signal representing rudder position and operates from a 24 V DC supply. The documented configuration specifies an external TDG 210-DG amplifier.
Before installation:
- Confirm the indicator model and part number.
- Verify the existing rudder feedback signal is compatible with the ±10 V input.
- Confirm the 24 V DC supply.
- Check the amplifier arrangement.
- Verify polarity and signal wiring.
- Compare the mechanical mounting arrangement with the existing indicator.
- Check the rudder-angle calibration after installation.
🛠️ Installation & Maintenance
The BW144 is intended for marine environments and has an IP66 protection rating. Even so, installation should protect the rear connections and cable entries from unnecessary mechanical stress and water exposure.
Recommended maintenance practices include:
- Inspect the front indicator and pointer for damage.
- Check mounting hardware periodically.
- Inspect cable glands and rear connections.
- Check for corrosion around terminals.
- Verify the 24 V DC supply.
- Confirm the analog rudder feedback signal.
- Check dimmer operation.
- Compare the indicated rudder position with the actual steering-system position.
- Recalibrate the indication if required by the steering system.
🔍 Troubleshooting
The pointer does not move
Check the 24 V DC supply, input signal, wiring, amplifier, and connector condition.
The indicated rudder angle is incorrect
Verify the ±10 V feedback signal and confirm that the indicator has been correctly adjusted or calibrated against the steering gear feedback.
The indicator moves in the wrong direction
Check input polarity and the signal assignment from the rudder feedback system.
The illumination or dimmer does not operate
Check the supply wiring and dimmer circuit. Inspect the housing and rear connections for moisture or corrosion.
The indicator operates intermittently
Inspect the analog signal wiring, terminals, connectors, power supply stability, and mechanical mounting. Marine vibration can also contribute to intermittent connection problems.
