in Digital Output : sometime when i turn a device ON the card gets disconnected and LED8 flashing i think theres a problem about connection
i didn’t use CLAMP port can i use it to solve this problem ???
also in digital inputs some times i get flashing on off on off even if the device has on all the time i used a relay when the device is on the relay with its connection will connects GND to any Digital Input then i get the input Value 0 or 1 its fine but sometime it keeps on off on off even if the relay on all the times
i connected outputs directly to drive relays with external power supply 12VDC (0-7)
i connected inputs with outputs of relays to GND of the k8055 with input Port (0-5)
To protect the output transistors of the board and to avoid transients that may disturb the operation of the card, it is good to connect the positive end of the relay coil to the CLAMP terminal.
