Fully redundant system
The OM-961M/OM-961S modules are designed to offer a complete redundancy solution for Onyx Marine systems.
The OM-961M module is the master unit and, once connected to a couple of OM-430B controllers and the double CAN-bus network, will handle switchover between master and backup controller, as well as primary and backup CAN-bus paths. The OM-961S module is a slave unit and used to handle switchover between primary and secondary CAN-bus paths at board or switchboard level.
Both modules feature fail-to-safe design, a redundant power supply and a number of I/O lines used for diagnostic purposes.
Like all Onyx Marine Automation components, these modules have been specifically designed for marine environments and the use of extended temperature range components (-20 to 85°C) and Type Approval certification make them an invaluable feature for a modern marine automation system.
