Product Description
Model: RRDIO15 Brand: Rolls‑Royce Marine (OEM manufactured by Weidmüller) Product Name: Digital Input‑Output I/O Module
RRDIO15 is high‑density digital I/O module dedicated for Rolls‑Royce Marine vessel alarm & monitoring system, DIN‑rail /19‑inch rack plug‑in mounting. It processes field binary signals, equipped with multi‑channel digital inputs and transistor digital outputs. It acquires dry‑contact signals from pressure switches, level switches and equipment status sensors, outputs discrete control signals for solenoid valves and local indicators. It communicates with RRWRC01 main controller via proprietary internal bus. Marine‑grade construction with excellent resistance to vibration, salt‑fog and wide‑temperature range. OEM end‑of‑life; available as new surplus, used or tested refurbished spare parts. Only compatible with Rolls‑Royce Marine proprietary system, cannot work with generic third‑party PLC。
