Wärtsilä Valve Remote Control System (VRCS) interfaces with the IAS (Integrated Automation System), with Mimic Diagram and with Emergency Shut Down (ESD) System. E-ACT-VCU technology has been developed for both Cruise and Mercantile Vessels. This technology is suitable for controlling electro-hydraulic actuated valves systems. This innovative technology and many years of successful experience enable us to provide turnkey solutions.
E-ACT-MB Motherboard can hold up to 8 E-ACT-VCU cards, thus controlling up to 8 valves. Each E-ACT-MB is equipped with following connections: redundant power Supply 24Vdc, redundant communication bus RS 485 and 230Vac power supply for E-ACT power.
Each E-ACT-VCU card controls one single valve and its feedbacks and interconnects with the IAS via communication cards or, optionally, directly through a Hardwire Interface. A number of LEDs on the Front Panel and others visible sideways, report the operating status of the card. Every card can be controlled locally via 3 simple push-buttons.
The SMART-PMD is a portable device, for maintenance purposes only, developed to operate during maintenance on WAPSS systems without cables connections. The SMART-PMD will connect wireless to VRCS cabinets under bulkhead deck, and can control all valves in cabinets installed in the same MVZ.
