125ºC Operation, 2 Quadature Encoder Inputs, 2 Outputs, SAE J1939
The 4 Inputs 2 Outputs Servo Controller is designed for versatile control of two servo outputs to directly drive servos or other bidirectional loads. In addition to the two servo outputs, there are two signal outputs with voltage and current signal generation. The controller’s flexible circuit design gives the user a wide range of configurable input types. The sophisticated control algorithms allow the user to program the controller for a wide range of applications without the need for custom software. The controller has two universal inputs that can be configured to measure analog voltage or current, frequency/PMW or digital signal and two analog inputs that can be configured to measure current and both positive and negative voltages. Measured input data can be sent to a SAE J1939 CAN Network or used to drive outputs directly or through the configurable control algorithms.
The servo outputs are full H-bridge types with the capability of driving up to 400mA through the load in both directions. The signal outputs can be configured to source voltage signals up to 10V and current signals up to 20mA. Any of the four outputs can be configured to use any of the on board inputs as either a control signal or an enable signal as well as SAE J1939 CAN Network data. A Windows-based Axiomatic Electronic Assistant® (EA) is used to configure the controller via an Axiomatic USB-CAN device. Setpoint configuration can be saved in a file which can be used to easily program the same configuration into another controller. The configurable properties of the controller are divided into function blocks, namely the Input Function Block, the Output Function Block, the Diagnostic Function Block, the PID Control Function Block, the Lookup Table Function Block, the Programmable Logic Function Block, the Math Function Block, the DTC React Function Block, the CAN Transmit Message Function Block and the CAN Receive Message Function Block. Packaged for rugged environments, the controller has an IP67 rating and is suitable for high vibration applications. It has CE marking.

Features:
The dual servo valve controller provides two bidirectional outputs from -400mA to +400 mA. The outputs will drive two servo valves independently. Two signal outputs are also provided for feedback to a PLC or other similar device.
An isolated SAE J1939 CAN port is provided for networking. Using the Electronic Assistant® programming tool, the user can select the desired inputs and outputs for common applications. The firmware was developed using Simulink®.
Two analog signal inputs are selectable as the following voltage or current signals (Inputs 1 and 2).
Two analog/digital inputs are available as the following signals (Inputs 3 and 4).
Two reference voltages (1 +5V and 1 +10V) are available to power sensors.
A rugged power supply interface accepts 8-36Vdc and is appropriate for battery powered machine applications. The circuitry is conformal coated and packaged in a rugged IP67 rated enclosure for harsh environments. It operates from -40 to 85°C (-40 to 185°F). It has CE marking.
