UMAX
DUAL PROCESSOR LMI DEVICE AND CAN-BUS INTERFACE
Product description
Main Unit "MASTER CAN BUS" with Freescale dual microprocessor, ON/OFF - analog voltage inputs, and ON/OFF - PWM voltage outputs. The unit includes a connected coupled relay and its command and commuting status is checked by each microprocessor. The application is specific for light access platform units as redundant geometrical or moment limiter device and as main dual processor system for advanced plants conforming to LEVEL IV of the EN280 standard.
