← TechnologyWhich risk increases when a PLC controlling an automated conveyor system experiences excessive electrical noise?
A)Spurious encoder signal interpretation✓
B)Increased motor winding inductance
C)Elevated ambient air temperature
D)Reduced sensor data transmission rates
💡 Explanation
Spurious encoder readings become likely because electrical noise can falsely trigger the PLC's input channels, causing misinterpretation of the encoder's position signals; therefore, the control system behaves erratically, rather than simply experiencing reduced data rates.
