Abstract
The sensor unit ( ) of the present invention comprises a housing ( ) which is adapted to be mounted on a DIN rail ( ) closely one next to another as a sensor unit array, and to be connected to a sensor head ( and ) via a cable ( and ). The housing ( ) accommodates a sensing circuit system ( to ) for achieving a desired sensing function in cooperation with the sensor head ( and ), a first optical communication circuit system ( ) including a light emitting device ( ) and a light receiving device ( ) for conducting an optical bi-directional communication with one of the adjacent sensor units in the multiple sensor unit array, and a second optical communication circuit system ( ) including a light emitting device ( ) and a light receiving device ( ) for conducting an optical bi-directional communication with the other of the adjacent sensor units, whereby the sensor unit ( ) is enabled to conduct an optical bi-directional communication with each of the adjacent sensor units in the multiple sensor unit array.
