Second generation CANbus keypads and MMI controllers
HMI specialist EAO has introduced second generation Joysticks and Man-Machine-Interface (MMI) Controllers that combine technical characteristics with easy toolless installation. Developed by Grayhill, the new 3J CAN-based devices feature enhanced shock resistance and long mechanical life and are built to withstand rugged conditions typically found in agriculture, construction, and mining machinery.
They provide built-in diagnostics and low-current consumption (less than 1.5mA when the system is inactive).
Grayhill's second generation joystick MMI controllers simply snap into the front of any control panel. They are designed for ISO 13849 safety-rated vehicle applications and meet the ISO and ANSI specifications, such as environmental sealing, temperature range and electrical conditions.
Providing multi-functional operation for intuitive operator control Grayhill’s new 3J generation two Joystick and MMI controllers are available in three mechanical form factors: the rotary encoder with pushbutton provides 16 position continuous rotation; the digital joystick encoder with pushbutton provides 20 position continuous rotation and the HE proportional joystick with push button has X-Y axes and also offers momentary rotation switching action. Each controller has six separate back illuminated push buttons with ISO legends or targets, and each pushbutton has three illuminated status indicators.
Designed for 12/24 volt systems Grayhill 3J Joystick and MMI controllers conform to J1939 - CANopen will be available soon, and CANbus safety communication protocols and offer a range of on-board self-diagnostics including supply voltage monitoring and button short detection indication. Operation verification indication is also provided, and all LED indicators and legends are dimmable. The new devices are field-tested to ensure more than 500,000 operations MTBF and are fully software compatible with Grayhill’s original Vehicle Display Controller (VDC).
The new Generation two MMI controllers are customisable in various ways including legends and indicators. The user can choose from green or white backlight colours and from a wide range of knob colours.
