Application
Purpose :
Electronic card used to set 2 timer sequences for a public washing machine.
Presentation :
Single parameterable card, controlled by 2 inputs to trigger the activation time for the 2 output relays (each input has an associated time that can be totalled up to 99). This card has two 7 segment displays that make it possible to show the time credit for the end user, as well as the
3 credit instructions for the maintenance technician. An intermediate timer can be activated using a jumper selection
system.
