What is plc sensor?
The PLC UV sensors and VIS sensors serve as precision sensors for the measurement of UV irradiances and illuminances in systems with programmable logic controllers (PLCs). Spectral range, measuring range, operating voltage, and output signal can be selected to match the measurement task and the PLC.
What is PLC logic controller?
A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices. Almost any production line, machine function, or process can be greatly enhanced using this type of control system.
