WARTSILA DESPEMES 3V72H115, C3/C5 RELAY CARD

This WARTSILA 3V72H115 C3/C5 relay card is a plug-in relay interface PCB for Wärtsilä DESPEMES marine engine monitoring and AUPA series automation system. The C3/C5 relay card converts main engine control logic signals into dry relay contact output for safety interlock, start/stop and alarm regulation. The C3/C5 relay card handles discrete signal switching for marine main engine auxiliary interlock and limit protection circuits. The C3/C5 relay card receives command feedback from engine speed sensors and shaft position pickups to trigger safety relay interlock. The C3/C5 relay card adopts marine grade circuit with conformal coating to resist salt fog, vibration and temperature fluctuation inside engine control cabinet.

This board performs relay signal isolation and safety interlock control for marine diesel main engine supervision. The DESPEMES relay interface module is equipped with channel LED indicators for on-site channel inspection and fault diagnosis. The DESPEMES relay interface module uses standard rack plug-in mounting for installation in DESPEMES dedicated control cabinet. The DESPEMES relay interface module supports signal isolation between marine main controller and field solenoid valves and alarm circuits. The DESPEMES relay interface module is widely fitted on bulk carriers, tankers and cargo vessels equipped with Wärtsilä DESPEMES engine monitoring system.

It serves as a vital spare relay control component for DESPEMES marine engine automation system overhaul and retrofit. The Wartsila 3V72H115 spare relay PCB is manufactured to original Wärtsilä factory specifications for direct plug-in replacement. The Wartsila 3V72H115 spare relay PCB ensures reliable safety interlock logic and reduces vessel downtime during engine control system maintenance work. The Wartsila 3V72H115 spare relay PCB supports simple wiring and fast on-site commissioning and channel testing. The Wartsila 3V72H115 spare relay PCB is stocked by global marine main engine automation spare parts suppliers worldwide.
