The AX020420 and AX020421 Valve Controllers can read up to 12 input command signals. These inputs may be voltage (0-5V or 0-10V), current (0-20mA or 4-20mA), PWM/frequency (1Hz-10kHz), or digital types. Six (6) inputs are also configurable as resistive (30Ω-250kΩ).
The valve drivers provide 12 outputs of up to 2.5 A each, but the module’s total output must not exceed 20 A). The outputs are user selectable as proportional voltage, proportional current, hotshot digital, on/off digital, or PWM.
The controllers have 1 CAN port. The AX020420 is SAE J1939 compliant with auto-baud-rate detection while the AX020421 supports CANopen®.
The devices feature a new microcontroller with more memory which allows the users to program it for a wide range of applications. The AX020420 can be configured using the Axiomatic Electronic Assistant without the need for custom firmware. Setpoint configuration can be saved in a file which can then be utilized to program the same configuration to another AX020420 device. The AX020421 comes with an EDS file for configuration.
An overview of software features of both models is provided below.

This new valve controller can operate with battery power supply of 8 V to 36 V and is protected against reverse polarity, surge and transient, and undervoltage faults. Its outputs have overcurrent and short circuit protection. It can work in temperatures from -40 to 85°C (-40 to 185°F). Its enclosure is rated IP67 against dust and water exposure.
These rugged qualities and functional flexibility of AX020420 opens the possibility of using it in a variety of applications like:
- High vibration and harsh environments of mobile equipment
- Off-highway and agricultural equipment
- Driving proportional poppet, spool, or On/Off hydraulic valves

Efficient valve drivers are responsible for the regulation of solenoids and hydraulic valves, including proportional valves. These drivers are operated via joysticks, switches, or sensors and are run with battery power. Our valve drivers can connect using protocols such as CANopen®, SAE J1939, and RS-232, among others. We offer a range of electronic controllers for mobile equipment with electro-hydraulics that feature both single and multiple inputs and outputs, designed to withstand demanding conditions.
