SAMSUNG SSAS-PRO SPIRU-16 versatile universal mixed I/O module
SAMSUNG SSAS-PRO SPIRU-16 is a versatile universal mixed I/O module engineered for marine automation, vessel monitoring systems, and heavy industrial process control.
Functioning as a high-efficiency interface within the Samsung SSAS-Pro (Ship Automation System Pro) architecture, the SPIRU-16 consolidates mixed signal channels into a single compact housing.
By combining digital inputs, digital outputs, and analog signal acquisition capabilities on a single card, the SPIRU-16 significantly optimizes panel space, reduces field wiring complexity, and provides flexibility for remote control cabinets and engine room sub-stations.
Application Cases
Shipboard Sub-System Control Panels: Serves compact auxiliary equipment rooms (e.g., bilge pumps, ballast valve controllers, steering gear sub-panels) requiring a mix of status inputs, alarm triggers, and control outputs.
Marine Engine Room Auxiliary Monitoring: Collects discrete limit switch states, monitors temperature/pressure transmitters, and drives local status indicators or alarm relays simultaneously.
Power Management Systems (PMS): Monitors breaker positions, system voltages, and fault contacts while executing generator control commands within local switchboards.
HVAC & Environmental Control: Handles temperature sensor signals, fan status inputs, and valve actuator control outputs across distributed vessel quarters.
Product Advantages and Features
All-in-One Signal Integration: Merges multiple signal types onto a single module, drastically reducing backplane slot consumption and hardware costs.
Optical & Galvanic Isolation: High-grade internal isolation shields sensitive system electronics from field electrical noise, ground loops, and high-voltage transients up to 1500V RMS.
Comprehensive Line Diagnostics: Features real-time loop fault monitoring, wire-break detection, and short-circuit protection across input and output channels.
Marine-Grade Reliability: Engineered to withstand severe engine vibration, high humidity, salt atmospheric corrosion, and fluctuating supply voltages in compliance with major marine classification standards (DNV, ABS, LR, KR).
Channel Status Indicators: Integrated front-panel LEDs provide immediate visual diagnostics for power, channel activity, and loop fault conditions.

Installation and Maintenance
Mounting: Secure the module onto the 35mm DIN rail or backplane rack inside the control cabinet. Ensure the ground tab securely connects to the grounded metal enclosure.
Field Wiring: Connect mixed field wiring according to the channel pinout diagram. Keep low-voltage analog signal lines segregated from high-voltage AC output wires.
Bus Connectivity: Plug in primary and redundant communication cables connecting the SPIRU-16 to the central SSAS-Pro controller frame.
Routine Maintenance: Periodically check terminal screw tightness in high-vibration engine environments. Ensure cabinet cooling vents are unobstructed to prevent ambient overheating.
