The 4 inputs, 2 outputs valve controllers generate 2 +/- 400 mA bidirectional outputs, user selectable as servo valve control or proportional current and are designed for versatile control of 2 servo outputs to directly drive servos or other loads. The flexible circuit design gives the users a wide range of configurable input types. The sophisticated control algorithms allow the users to program the controllers for a wide range of applications without the need for custom software. The controllers accept 2 universal inputs that can be selected as voltage, current, frequency/PWM, or digital signal and 2 analog inputs that can be selected as current or voltage. The controllers feature Near Field Communications (NFC) and can send measured input data to a CAN network (SAE J1939 or CANopen®) or use the data to drive outputs. The valve controllers are user configurable via the E-Write NFC application that is available for download for Android and Apple iOS and either standard CANopen® interface tools (not supplied) or the Axiomatic Electronic Assistant.

The E-Write NFC application for Android and iOS devices is available for download from the Google Play Store and the Apple App Store for a fee.
