The SDU 410 is an independent, engine safety shutdown module designed to provide the functionality required to meet Classification Society Rules up to and including UMS notations. Equipped with eight switch channels for normally open (NO) switches, and inputs for two-speed sensors, complete with wire break detection, the SDU 410 also provides for short circuit detection and protection.
The unit also has warning LED’s for each channel reflecting these fault conditions to assist troubleshooting. With its own built-in web server, the SDU is automatically configured by the DCU module when connected via the simple two-wire SDU link. The unit can also be used independently and programmed using an Ethernet cable and any computer with a web browser.
Why more customers select the SDU 410
The combination of the SDU and DCU allows customers to be selective. Why pay for the functionality of Classed shutdowns if you do not need it? Simple DIN rail fitment means easy installation, and connectivity is clear via the printed connection diagram on unit, plus no special tools. The ability to configure the unit – without any interaction – when connected to a DCU, means significant savings in the resource.
The SDU, even when functioning as a “standalone” unit is still connectable to the Ethernet by a standard Ethernet cable, so the information and events are readily available to the ships systems when required.
