Description
The SAMSUNG SSAS-PRO SPDI-16 Alarm Monitoring System Digital Input Module is a marine automation remote I/O module designed for ship alarm monitoring, machinery supervision, and integrated control systems. It is part of the Samsung SSAS-Pro (Samsung Automation System Pro) platform and provides digital signal acquisition from field devices.
The SPDI-16 receives discrete signals from switches, alarm contacts, sensors, and monitoring devices installed throughout the vessel. It transfers collected status information to the SSAS-Pro central processing unit for alarm handling, event monitoring, and automation control functions.
This module is commonly used in engine room automation systems, marine integrated automation systems (IAS), and industrial monitoring applications requiring reliable digital input processing, fault detection, and continuous operation in harsh environments.
