MSD 77643 Power Grid Power Module - 80 Amp 4-Channel Relay Controller Black

The MSD 77643 Power Grid Power Module is a solid-state electronic power distribution solution that replaces traditional electromechanical relays with advanced digital control. This black-finished module offers 80 amps of total capacity distributed across four independent channels, each rated for up to 20 amps of continuous power.

Key Features:

• Replaces up to 4 traditional electromechanical relays with solid-state switching
• 80 amp total capacity with 4 independently controlled 20-amp channels
• Built-in overcurrent protection eliminates the need for external fuses
• Can be used as a standalone power controller or integrated with MSD Power Grid system (PN 7730)
• Multiple trigger signal options including power, ground, temperature, or time-based activation
• Each channel controlled via dedicated input wires or through MSDView software programming
• Data acquisition capability when connected to MSD Power Grid system
• Available in black (PN 77643) or red (PN 7764) finish

This power module is ideal for racing applications, performance vehicles, and custom electrical systems where reliable, programmable power distribution is critical. The solid-state design provides faster switching, longer service life, and eliminates the clicking noise associated with mechanical relays.
