CZone™ Signal Interface

The Signal Interface (SI) connects the CZone™ system to your external sensors, alarms and switching devices. The SI allows intelligent, automated operation of circuits depending on the state of the input.

• Accepts inputs from traditional switch types being used to control outputs
• Accepts inputs from switches to trigger alarm i.e. high water float switch
• Accepts inputs from industry standard tank senders (0-5V, 10-180 Ohm, 240-33 Ohm)
• Accepts inputs from general voltaic or resistive signals can be used for controlling outputs or to display a physical position i.e. show a hatch is partially open
• LED status indicators for each input
• Dimensions, WxHxD: 156x100x42mm
• IPX5 water ingress protection
• Resistive input range 0–1000 Ohms
• Outputs standard NMEA 2000 sentences
• Voltage sensing input range 0–34V DC
