AX022440: Dual Input/Output Valve Controller, DIN rail

The Dual Valve Controller is designed for extremely versatile control of up to two proportional outputs to
directly drive coils or other loads. Its flexible circuit design gives the user a wide range of configurable input or
output 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 fully programmable universal inputs that can be setup to read: bipolar or unipolar
voltage, current, resistive, frequency, or digital input signals. There are also two universal outputs that can be
setup to drive: proportional current (up to 2.5A each); hotshot digital current; proportional voltage (up to
supply); proportional PWM; or straight on/off digital loads. All I/O ports on the unit are independent from one
The controller is a highly programmable controller, allowing the user to configure it for their application. Its
sophisticated control algorithms allow for open or closed loop drive of the proportional outputs. It can be
operated as either a self-contained control system, driving the outputs directly from the on-board inputs,
and/or it can be integrated into a CAN J1939 network of controllers. All I/O and logical function blocks on the
unit are inherently independent from one another but can be programmed to interact in many ways.
It has several built-in protections that can shut off the outputs in adverse conditions. They include hardware
shutoffs to protect the circuits from being damaged as well as software shutdown features that can be
enabled in safety critical systems.
All setpoints are user configurable using the Electronic Assistant.
A rugged power supply interface accepts 12 Vdc or 24 Vdc nominal for battery powered machine
applications. An LED indicates operational status. The enclosure is DIN rail mount. It operates from -40 to
85C (-40 to 185F). The sophisticated control algorithms allow the user to program the controller with the Electronic Assistant.
