Sensor Interface Units (optional)

Sensor Interface Units are an available option in the Octoplex Multiplexed Management System. Analog alarm and status monitoring devices are connected to the bus through Sensor Interface Units (SIU). Standard SIUs will provide up to 32 analog inputs and may be located throughout the vessel to collect error signal or analog parameters from critical systems such as high water alarms, heat and fire alarms, fuel systems, water systems, etc. A dedicated SIU, the Battery Monitor Unit (BMU), will collect and transmit essential battery bank monitoring information, including voltage, amperage, and battery temperature. Each Sensor Interface Unit will process the analog signals, convert them to digital, and transmit the information on the bus to all control panels. All interface units are designed and manufactured to meet or exceed the marine ABYC watertight enclosure environmental requirements for salt, fog, and spray.
