How do digital input work How do digital output work What's plc scaning time How many type off timer in plc How do interlock with logic

Question

Accepted Answer

Digital inputs and outputs in PLCs work by receiving or sending binary signals, PLC scanning time is the time taken for the PLC to complete one scan cycle, PLCs have different types of timers for various functions, Interlocking in PLCs is achieved through logical programming.

Digital inputs in PLCs receive binary signals from sensors or switches
Digital outputs in PLCs send binary signals to actuators or devices
PLC scanning time is the time taken for the PLC to complete one scan cycle, which includes reading inputs, executing logic, and updating outputs
PLCs have different types of timers such as on-delay, off-delay, and retentive timers for controlling time-based functions
Interlocking in PLCs is achieved by using logical programming to ensure that certain conditions must be met before a process can proceed
