ILLUSTRATED ASSEMBLY MANUAL H2633IP-1 Total solder points: 92 Difficulty level: beginner 1 2 ; 3 4 5 advanced “Control up to 4 high-power circuits from a low-power drive circuit.
The connection of a few relays to the outputs of an electronic circuit might be theoretically very simple, but practically it may lead to a very complicated matter with all possible results. This kit is an attractive and compact alternativ, fast to construct and to mount. It can be used with open collector circuits. Features: y Four relay outputs, single pole invertors y Max. load : 240V AC / 3A resistive y 9V DC / 300 mA power supply y Four control-LED's are provided y Is controlled by an open collector output (9V/15 mA) y Dimensions : 76 x 69 x 25 mm. Features & Specifications
- 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. 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 components 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
1.2 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 drawings. ⇒ 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. 0.000
1.3 Soldering Hints :
1- Mount the component against the PCB surface 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 REMOVE THEM FROM THE TAPE ONE AT A TIME ! AXIAL COMPONENTS ARE TAPED IN THE COR- RECT MOUNTING SEQUENCE !

Construction & connection 7. Connection Connect the power voltage of the relay to the 9V DC points. * This voltage needs not to be stabilised. The connection of the loads to the relays is very simple : at the outputs the name of the contact is given.
- C stands for the common contact.
- NC for the contact of the inverter that is closed in rest.
- NO for the normal open contact. In most cases you will only use C and NO. * In order to avoid disturbances and bum-in of the contacts when switching inductive loads (motors, heavy-duty-relays, ...) we recommend to install a VDR over the contacts. When this should not be an adequate cure against disturbances in the control circuit, you have to place the relay print nearby the load itself.
