The Terasaki EMW-1301 is a specialized analog input interface module designed for marine power station automation and engine control systems. It acts as the critical bridge between field sensors/transmitters (e.g., temperature, pressure, voltage, current transducers) and the main control unit, performing analog signal acquisition, isolation, filtering, and conversion. This module processes standard industrial signals (such as 4–20 mA, 0–10 V, thermocouple mV, and RTD signals) into conditioned digital data for real-time monitoring and control. Equipped with robust isolation circuits and EMC protection components, it ensures reliable data transmission in harsh maritime environments characterized by high vibration, salt spray, and electromagnetic interference. It integrates seamlessly into Terasaki’s EMW-series control system architecture, forming a complete data acquisition chain for shipboard power management and machinery condition monitoring.
