- Page 2 Features & Specifications Applying relays is the most usual way to switch an alternating current (AC) with an electronic control, because of its simplicity and its security, as the switching and switched voltage are completely separated. The low speed (esp. for illuminated advertisements ) and the short life of the contacts are however major disadvantages.
- Page 3 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.
- Page 4 Assembly hints 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 !

- Page 7 Connection 7. Connection Connect the minus side of the inputs to the open collector outputs of the interface card(s) (see fig.1). Connect the positive side of all inputs with a control voltage (ex. +9Vdc to 12Vdc). The negative (GND) of the control voltage must also be connected to the Common (or GND) of the open collector card. Keep in mind that EACH input of the triac card takes about 12mA from the power supply ! This control voltage has to be COMPLETELY ISOLATED! To supply the card a separate supply must be used of 9Vdc (see fig.
- Page 8 Connection ATTENTION : everything on the print from the optocouplers to the output side is subjected to this (eventual) hazardeous voltage. The loads are connected to OUT1 and OUT4. Interferences on the mains are possible because of the fact that the load switching does not necessarily takes place on the zero crossing point of the AC.
