XD Series NMEA 2000 Dual - Relay/Relay with Knobs

Bi-Stable Relays & Advanced VSRs/ACRs with NMEA 2000

• NMEA 2000 controllable, while also responding to optional discrete remote controls
• Reports switch status, status of manual override knobs, and battery voltage on input terminals to the NMEA 2000 network
• Optional manual override knobs provide ability to lock switches ON or OFF for servicing or if control power is lost
• Simple programming via dip switches for NMEA 2000 instance selection and battery voltage reporting, and Close/Open set-points on voltage sensing relays in Dual/Triple XDs
• Local LED, optional Remote LED, and NMEA 2000 On/Off indication for each switch
• 500 Amp max continuous current per switch
• 4 Year Industry Leading Warranty

Flexible Application Options
Configure each XD switch as a Relay or Voltage Sensing Relay (VSR). On/Off triggers via NMEA 2000 digital switching signals, external analog control signal or automatic voltage sensing via advanced algorithm (when set as VSR).

Diagnostic Feedback
Via NMEA 2000 messaging and on-board LEDs for each switch.

Simple & Robust Installation
Sealed DT/AT and standard M12 NMEA 2000 connectors.

Low Power Draw
Low standby power draw of 15 mA combined.

Meets Stringent Electrical Standards
Standards for electrical load dump, mutual coupling, transients, and EMI Emissions and Immunity.

Bullet-proof Construction
Sealed unit, high temperature materials allow mounting anywhere. Tin plated copper alloy condustors and stainless steel hardware.

Battery Voltage Reporting
Via NMEA 2000 network messaging, outputs to report are selectable via local dip switches.

ACR/ VSR what is the difference:
The main difference between an ACR and a VSR is their functionality and application. An ACR is designed to automatically connect and disconnect batteries based on the presence of a charge source, ensuring that critical batteries retain sufficient power. In contrast, a VSR is a type of ACR that specifically monitors line voltage between battery banks and automatically connects them in parallel when a charging source is present, isolating them when the source turns off. This dual functionality allows for more complex battery management systems, where both isolation and connection are needed.
