The relays can be controlled in different ways : direct
control from open-collector outputs, TTL or CMOS level or
trough other kits (K6711, K8000, K8023,...)
DIP switches are included to allow manual activation of the
relays in case of maintenance work.
Every output of the print can be equipped with a noise suppres-
sor network.
Output 12V CC can be used as a power supply for other kits:
K6711, K8023,...
K6714
8 output relays

- Page 10 Test and connections TEST AND CONNECTIONS : Connect the phase to “0” and the Neutral to “125” or “220”, depending on the mains voltage. Normally the POWER ON LED should be lit now. In case no manual operation has been provided, you can test the relay by connecting the inputs (terminals 1 trough 16) to earth (GND) one after another.
