Model: RRAIO16 Brand: Rolls‑Royce Marine Product Name: Analog Input‑Output Alarm I/O Module
RRAIO16 is a high‑density integrated analog I/O alarm module co‑developed by Rolls‑Royce Marine and Weidmüller, DIN‑rail mounting, dedicated for marine propulsion and offshore power‑generation control systems. It features 16 configurable channels for analog, digital and pulse‑frequency signal acquisition, together with analog output control capability. Built‑in galvanic isolation provides good immunity against vibration, salt‑fog and wide temperature variation. It acquires field sensor signals such as temperature, pressure, liquid level and flow, and transmits data to vessel management system and central alarm monitoring unit
