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. Key Features Input protection: Handles up to 1,500V peak, 33.5V continuous Inverting digital output: 0 to system supply voltage (5.0V to 29.0V) Water-resistant: PCB is conformal coated for moisture protection (do not submerge) Durable connection: Includes Amphenol AT connector (Deutsch DT compatible) with pre-crimped pins Compact & reliable: Designed for motorsports and rugged environments Technical Specs Input Voltage Range: 6.2V to 33.5V continuous Peak Transient Voltage: 1,500V Output: Inverting, 0 to system voltage System Voltage Range: 5.0V to 29.0V
