AI- Analog input (that means 24volt dc with 4-20madcdriving
the loop)
AO- Analog Output (that means only 4-20 madc driving the
loop)
D/I - Digital input (5volt/15volt/24volt/110volt supply
given from plc to the field switches
(pressure,level,limit,flow)to close the circuit or breake
the circuit.
D/O - Digital Output (PLC giving output voltage mode
24volt/110 volt to the field either solenoid valve or
electrical driven equipments

Lux meter is the measuring device to measure the lux level of lighting fixture. in industrial sector two types of lighting fixture is being used as street lighting purpose 1. HPSV (Sodium) and 2. HPMV (Mercury). HPMV having white light which is an combination of red, blue and yellow colour, while HPSV haivng Yellow lighting. in HPSV red & blue colour will be absent. during measurement of the lux level of HPSV and HPMV fixture. 1. Lux meter can measure the actual lux level of both fixture? 2. or it will show false reading for HPSV fixture light as it has only yellow light present. please give me answer
