Universal Relay Card K6714 & K6714 - 16 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.

Noise suppression Noise suppression of the relay contacts “OPTIONAL !” : At the standard module K6714 as well K6714-16 have you the opportunity to noise-suppress every relay contact. First : mount the resistors to noise-suppress the normally open contact of the relay : ...

K2609 and K8000. The module can of course also be used very well in other applications. OPTIONS : In its standard version the module contains 8 relays (K6714), but in the full version the module (K6714-16) contains : 16 relays.

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.

Tips at malfunctions Remedies in the case of malfunction cused by the relays If the relays are used to switch alternating voltage, it may be necessary to suppress them. Suppressing resistive loads (Lamp, resistor,…) : FIG. 3.1 Suppressing inductive loads (Transformer, motor,…) : FIG 3.2 When above solutions fail : In this last case an independently feeded DC-relay is used, wich is installed as...
