Edge Triggered Wiping Relay
The edge-triggered wiping relay allows a rising edge at the input Tr to generate a set number of pulses at the output Q. The parameter TH defines the on duration of the pulse and the parameter TL defines the off duration. The parameter N is the number of pulses for each rising edge at Tr. Every time Tr is triggered the timer of the pulses is reset and begins counting again.
If the input R is triggered, the timer is reset and the output Q is disabled, and only if Tr is triggered is the timer started again.
The block can be set to be retentive, this is done by clicking on the battery symbol to set the red NOT dot on the block (input is by default inactive).
