一般說明

The "BS10-PLC" has been designed to study different light measurement techniques and control light intensity through a PLC. This unit is composed of a lamp whose intensity can be controlled according to the voltage applied and a series of transducers for the measurement of light intensity. One of the light sensor output signal is conditioned to be connected to the PLC. The light intensity can be controlled by a PLC managing the lamp light intensity, depending on the values obtained by a light sensor.

* Available PLC models of different manufacturers: PANASONIC, SIEMENS, OMRON, MITSUBISHI, ALLEN BRADLEY, etc.
