Assembly hints

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.

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. When solder rolls off the tip, it needs cleaning.
• Thin raisin-core solder. Do not use any flux or grease.
• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot fly towards the eyes.
• Needle nose pliers, for bending leads, or to hold compo- nents in place.
• Small blade and Phillips screwdrivers. A basic range is fine.
  • For some projects, a basic multi-meter is required, or might be handy

Assembly Hints:

• Make sure the skill level matches your experience, to avoid disappointments.
• Follow the instructions carefully. Read and understand the entire step before you perform each operation.
• Perform the assembly in the correct order as stated in this manual
• Position all parts on the PCB (Printed Circuit Board) as shown on the draw-ings.
• Values on the circuit diagram are subject to changes.
• Values in this assembly guide are correct*
• Use the check-boxes to mark your progress.
• Please read the included information on safety and customer service

Typographical inaccuracies excluded. Always look for possible last minute manual updates, indicated as ‘NOTE’ on a separate leaflet.

Soldering Hints:

1. Mount the component against the PCB sur-face and carefully solder the leads
2. Make sure the solder joints are cone-shaped and shiny
3. Trim excess leads as close as possible to the solder joint

Construction

IMPORTANT
To use the relay card with 16 relay outputs, mount the components marked with (*) also (K6714-16).

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:

• R19, R21, R23, R25, R27, R29, R31, R33 : 220Ω/0,5W
• R34, R36, R38, R40, R42, R44, R46, R48 : 220Ω/0,5W (*)

Or mount the resistors to noise-suppress the normally closed contact of the relay:

• R18, R20, R22, R24, R26, R28, R30, R32 : 220Ω/0,5W
• R35, R37, R39, R41, R43, R45, R47, R49 : 220Ω/0,5W (*)

Next mount the capacitors:

• C1…C8 : 100nF/400V – Type : .1/250A or 15MQ100.
• C9…C16 : 100nF/400V – Type : .1/250A or 15MQ100 (*)

To use the relay card with 16 relay outputs, mount the components marked with (*) also (K6714-16).

Important Instruction

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. The module can also be used together with the open collector interface module 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.
• DIP switches for manual operation.
• An indication LED per relay.
• Two ULN2803 type transistor array (IC’s).

You can fit the standard module K6714 with another 8 relays (12V types) your- self. However this requires the installation of additional screw connectors.

• The ULN2803 type transistor array allows you to control the relays direct from a TTL or CMOS. For controlling the relay with open col-lector control, don’t mount the transistors arrays.

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)
2. Connect the board to the 10 channel, 2 wire remote control K8023 (see Fig. 2.0):

Tips at malfunctions

Remedies in the case of malfunction caused 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,…):

2. Suppressing inductive loads (Transformer, motor,…):

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.

4. Pay attention to the diode witch is fit ANTI-parallel with the coil, its cathode connected to the plus side, its anode connected to the minus side! This relay MUST be feeded by a separate power supply. The VDR must be suited for the voltage to be switched.

INFORMATION FOR UPGRADING YOUR MODULE!
Components necessary to upgrade the K6714 to K6714-16 “16 Relay out-puts”:

OPTION: Noise suppression of the relay contacts:

or 1/250A

• The quantity shown only pertains to the K6714 with an 8-relay output. Double the quantity if you wish to extend your standard module to a 16-relay output.
• (*) Simply double the quantity if you have the K6714-16 kit.
