Product Overview
The SAMSUNG SSAS-PRO SPDO-16 is a 16-channel opto-isolated digital output module built exclusively for the Samsung SSAS-PRO shipboard alarm and monitoring system. This rack-mounted hardware converts alarm commands from the main system controller into discrete 24VDC switching signals for field marine equipment, solving signal triggering and electrical isolation challenges within vessel automation cabinets. Marine electrical officers, shipyard automation engineers and vessel maintenance crews rely on SAMSUNG marine modules for consistent alarm execution and compatibility with established onboard monitoring infrastructure. The unit supports multi-point alarm actuation, delivers robust noise suppression for engine room environments, and enables flexible expansion of safety interlocks and visual alarm indicators across commercial vessels.

Key Functions
- 16-Channel Isolated Digital Alarm Output: Each independent opto-isolated channel delivers 24VDC switching signals to alarm lamps, buzzers and auxiliary relay circuits. Galvanic isolation blocks electrical interference from power equipment to protect the main SSAS-PRO controller hardware.
- Backplane RS485 System Communication: The module communicates over the dedicated SSAS-PRO rack bus to receive real-time alarm trigger instructions. Synchronised data exchange ensures fast, consistent output activation when machinery threshold violations are detected.
- Per-Channel Short-Circuit Fault Protection: Built-in circuit protection limits damage during field wiring faults. Faulty channels are isolated automatically, preventing a single wiring error from disabling the entire bank of alarm outputs.
- Modular Rack Expansion Architecture: Designed for slot installation within standard SSAS-PRO cabinet racks. Multiple modules can be added to scale alarm output capacity without replacing the core monitoring system controller.
Application Scenarios
- Commercial Cargo Vessel Engine Room Alarm Systems: Installed inside main alarm cabinets to drive high-temperature, low-pressure and overspeed visual/audio alarms. The SAMSUNG module ensures timely crew notification of auxiliary machinery deviations to avoid equipment damage.
- Offshore Vessel Safety Interlock Control: Triggers ventilation shutdown, fire damper actuation and emergency warning devices during hazardous condition detection. Reliable switching performance supports compliance with marine safety operational requirements.
- Vessel Automation Retrofit & Spare Replacement: Widely used during dry-dock refits to replace ageing output modules. Identical mechanical footprint and native SSAS-PRO protocol compatibility eliminate complex rewiring and system reconfiguration work.
