AXM-110 High Voltage Isolator

The AXM-110 is a high-voltage isolator module designed to protect your engine or transmission controller from damaging voltage spikes on digital input lines. Whether you're working with older ignition systems or high-powered accessories like line locks and transbrakes, this module keeps your control electronics safe.

Built with robust electrical isolation and compact motorsports-grade packaging, the AXM-110 is ready for harsh environments and demanding applications.

Common Applications

• Fuel-only installs: Trigger an MS3Pro EVO from the coil (-) terminal on a distributor-based ignition system

• Carbureted transmission control: Isolate high-voltage trigger inputs on MicroSquirt TCU setups

• Safe integration: Add protection for line locks, transbrake solenoids, and other inductive loads tied to ECU/data logger inputs

⚠️ Not recommended for CDI ignitions—use the CDI’s built-in tach output instead.
