HIGH COUNTRY TEK - EVC, Electronic Valve Controller - A Multi-Function SAE J1939-Compatible Module

The EVC is one of the most versatile and precise electronic valve controllers on the market today. Configured using an intelligent graphical user interface (GUI), the EVC can be used in simple proportional single- and dual-coil applications or in more complex closed-loop pressure/speed control solutions. The command signal can be either industry standard voltage ( 0 to 5 or 0 to 10V ) or current ( 4 to 20mA ) while the mobile industry can take advantage of the SAE J1939 compatibility for horsepower limiting or anti-stall applications.

The EVC module has been designed to be a cost-effective solution to many of today's valve control projects. Designed with two 12-bit 3.0-amp outputs, the EVC is compatible with a wide range of 12- and 24-volt coil requirements and manufacturers. The unit uses standard Deutsch connectors, operates with minimal wiring requirements and is fully encapsulated to protect to IP67, meaning it can be mounted externally in extreme environments to save costly enclosures.

Take advantage of set-up tools such as data logging and real-time graphing via the GUI in addition to the save/load functions for repeatability and configuration management. The EVC has an industry unique feature where it can be powered by the mini-USB for desktop configuration while the coil output is turned off but GUI and parameter settings are fully operational, making this an ideal product for multiple functions. In short, you can do more with the EVC.
