ILLUSTRATED ASSEMBLY MANUAL H6714(16)IP-ED1

þ 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,…)

þ DIP switches are included to allow manual activation of the

relays in case of maintenance work.

þ Every output of the print can be equipped with a noise suppres-

sor network.

þ Output 12V CC can be used as a power supply for other kits:

K6711, K8023,...

Specifications :

Ÿ Power supply: 230 or 125VAC max.

12VA.

Ÿ Output voltage: 12V/250mA.

Ÿ Relay switch-over contact : max.

5A at 220V.

Ÿ Dimensions : 150 x 212mm

Assembly hints 1. Assembly (Skipping this can lead to troubles ! ) Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully. 1.1 Make sure you have the right tools: • A good quality soldering iron (25-40W) with a small tip. • Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and enables you to make good connections.

Construction IMPORTANT G To use the relay card with 16 relay outputs, mount the components marked with (*) also (K6714-16). TIP : The pictures on the packaging can be used as a guideline. However, due to possible changes it is not 100% reliable. Mount the components in the order described : 1. Jumperwires 4. LED’s (Watch the polarity!) q J LD...

Noise suppression 13. 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.

Important ! 14. IMPORTANT : If you want an electronic controller to be able to switch higher currents and at the same time you need an insulation between the controller and the controlled items, then a relay module is an indispensable help. The module is very well suited to be connected to our kits K6711 (15 channel IR receiver) and one or two times K8023. For those two kits power can be taken direct from the relay module.

Test and connections 15. 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. Connections possibility's : 1. Connect the board to the 15 channel receiver K6711 (see Fig. 1.0) FIG 1.

Test and connections 2.

Tips at malfunctions 16. 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. 1. Suppressing resistive loads (Lamp, resistor,…) : FIG. 3.1 2. Suppressing inductive loads (Transformer, motor,…) : FIG 3.2 3. When above solutions fail : In this last case an independently feeded DC-relay is used, wich is installed as close to the load as possible. G FIG 3.
