Axiomatic designed a Simulink model-based design tool-compatible controller series for engine or underhood installation. The fan drive controller platform, AX022600S, accepts two inputs, one Hall-effect sensor or digital/ pulse width modulation (PWM) signal input, and provides a 4-A output to drive a solenoid. The unit operates with 12- or 24-V dc power over -40 to 125°C (-40 to 257°F). The CAN-controlled PWM valve driver with feedback, AX022810, controls an actuator. It accepts one universal signal and frequency sensor input and provides a 4-A digital or PWM output. Power is 12- or 24-V dc nominal with a -40 to +105°C (-40 to +221°F) range. Both designs feature an aluminum enclosure, encapsulation, gasket, 12-pin connector, and an IP67 rating and are suitable for off-highway vehicle and truck applications.
