WebbA timer is a PLC instruction measuring the amount of time elapsed following an event. Timer instructions come in two basic types: on-delay timers and off-delay timers. Both “on-delay” and “off-delay” timer instructions have single inputs triggering the timed function. An “on-delay” timer activates an output only when the input has ...

Timers are devices that count time increments. The timer creates a delay in both PLC programming and in relay boards on connection or instantaneous disconnection. Simply, when the input is activated the timer starts its operation keeping track of the time. ricky carruth gold bar
