XD NMEA 2000 Dual Relay/VSR with Knobs 8-Pin DT ConnectorXD NMEA 2000 Dual Relay/VSR with Knobs is a high-power, dual-circuit marine and vehicle electrical management device. It combines a remote battery switch and an Automatic Charging Relay (ACR) / Voltage Sensing Relay (VSR) into a single compact, programmable module.Features: NMEA 2000 Integration: Allows seamless remote control and real-time monitoring of battery voltage and switch status directly from compatible Multi-Function Displays (MFDs). High Capacity: Supports continuous loads up to 500A and cranking loads up to 1600A per switch, making it suitable for heavy-duty marine or work truck systems. Manual Override Knobs: Includes intuitive 3-position local knobs that allow you to manually force relays Open or Closed and lock them in place. Smart Charge Management: Eliminates dead start batteries by automatically sharing charging sources (e.g., an alternator) and isolating batteries when no charging is present. Programmability: Easily configurable via built-in dip switches to customize voltage offsets and delay settings. Bulletproof Construction: Sealed to IP67/IP6K9K standards, featuring high-temperature electronics and corrosion-resistant stainless-steel hardware. table.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; } Truck Freight: No Oversized: No
