750-600 - END MODULE

THIS DIGITAL INPUT MODULE RECEIVES CONTROL SIGNALS FROM THE FIELD SIDE AND SUPPLIES A SHORT-CIRCUIT PROOF VOLTAGE TO THE SENSORS. THE MODULE TRANSFERS THE CONTROL SIGNALS AND OTHER INFORMATION VIA A FIELDBUS COUPLER TO THE HIGHER-LEVEL CONTROLLER.EACH INPUT MODULE HAS A NOISE-REJECTION FILTER.EACH SENSOR CAN BE SUPPLIED SEPARATELY. A SHORT CIRCUIT TO GROUND IS INDICATED AS AN ERROR/FIELDBUS FAILURE AND A MESSAGE IS SENT TO THE SUPERVISORY CONTROL.THE ERROR IS CANCELED AUTOMATICALLY AFTER IT HAS BEEN RECTIFIED.FIELD AND SYSTEM LEVELS ARE ELECTRICALLY ISOLATED.

AFTER THE FIELDBUS NODE IS ASSEMBLED WITH THE CORRECT BUSCOUPLER AND I/O MODULES, THE END MODULE IS SNAPPED ONTO THE ASSEMBLY.

IT COMPLETES THE INTERNAL DATA CIRCUIT AND ENSURES CORRECT DATA FLOW.
