The Universal 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: voltage, current, resistive, frequency, or digital input signals. It also interfaces with a magnetic pick up sensor and an encoder. There are also two universal outputs that can be setup to drive: proportional current (up to 3A each); hotshot digital current; proportional voltage (up to supply); proportional PWM; or straight on/off digital loads. The universal output type is user selectable as high side, low side or half bridge output. All I/O ports on the unit are independent from one another.
The valve driver 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.
The valve controller 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.
Setpoints are user configurable using E-Write NFC Android Application and for complex control profiles, the Electronic Assistant.
A rugged power supply interface accepts 12 Vdc or 24 Vdc nominal for battery powered machine applications. LED’s indicate 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 for a wide range of applications without the need for customer software.
