Kongsberg Simrad MOS-33 TFT Midi Operator Station 8200635

Kongsberg Simrad MOS-33 TFT Midi Operator Station 8200635

Kongsberg Simrad MOS-33 TFT Midi Operator Station, a multipurpose operator station designed for alarm monitoring and process control. 

The MOS-33 features a 5.7-inch color TFT display and an integrated keyboard, providing a complete HMI solution in a single unit. 

It is built to withstand extreme temperatures, shock, and vibration, making it suitable for installation anywhere on a vessel, from the bridge to the engine room or even on deck.

Technical Specifications

Display: 5.7-inch color TFT, 320 x 240 pixels.

Power: 18-32 VDC.

Operating Temperature: -15°C to +70°C.

Approvals: DNV Class B, IACS E10.

Interface: Integrated keyboard with menu, function, and alphanumeric keys.

Applications & Compatibility

Alarm and process monitoring in space-constrained locations.

Dedicated control panel for specific machinery or remote alarm panel.

Use as a remote operator station in harsh environments (engine rooms, on deck).

The Kongsberg Simrad MOS-33 (Midi Operator Station) is a compact, multipurpose operator panel designed for monitoring and control in maritime environments.

1 It is often used as a remote alarm station or a secondary control interface for systems like K-Chief 600. AutoChief, and Bridge Watch Monitoring Systems (BWMS).2

+1

Unlike larger PC-based operator stations, the MOS-33 is a "midi" unit, meaning it is ruggedized for installation in harsh areas like engine rooms or even out on deck.3

Key Technical Specifications

The MOS-33 integrates both a display and a functional keyboard into a single, compact housing.4

Functional Design

The front panel is designed for high-visibility alarm management and simple process control through tactile buttons:

Keyboard Layout: Includes 4 dedicated Function keys (F1–F4), a numeric/alphanumeric keypad, and dedicated navigation keys for menu scrolling.5

Alarm Management: Features large, tactile buttons for Acknowledge (ACK) and Sound Off, allowing for immediate response to system alerts.

Symbol Library: The internal software includes a library of symbols used to display standard mimic diagrams for pumps, valves, and power management.

Relay Outputs: Typically includes 2 relay outputs for local buzzer or lamp control.

Common Applications

Remote Alarm Panel: Placed in cabins or the mess room to alert the crew of engine or system alarms.6

Machinery Control: Used as a local control panel for specific subsystems like a steering gear or compressor.7

Bridge Watch (BWMS): Often serves as the primary setup and reset panel for the Bridge Navigational Watch Alarm System, where it monitors officer alertness.

Troubleshooting & Service Notes

Backlight Dimming: If the screen appears black but the unit has power, the backlight may be failed or dimmed to 0%.

 Try pressing the brightness increase shortcut (usually a combination of the 'Menu' and arrow keys).

Environmental Damage: While rated for deck use, ensure the removable corner covers used for flush mounting are properly sealed to prevent water ingress behind the console.

Firmware/Configuration: The MOS-33 stores local configuration data. If you are replacing a unit, you may need to transfer the configuration or re-assign its ID on the CAN bus or Serial network for it to communicate with the main DPU
