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. In order to avoid the disadvantages of the relay without losing the advantages, optocoupler controlled triacs are used. Because of the fact that the outputs are controlled by current instead of voltage, they are less sensitive to input interferences, so that the triac card can easily be mounted near the load and relatively far from the control circuit (e.g. for score boards etc.). This kit can immediately be connected to cards like: K8000, K8050, K8023, K8055, K8046, K8055 or other cards with open collector output. Circuits which can deliver a control current of 10mA or higher can also be used. Features: Four triac outputs Inputs galvanically isolated by optocouplers. 4 control LED s are provided Specifications: Load : 24 to 240V AC, 0,5 A not cooled (max. 4A) per output. Control current : 10 to 20mA DC. 9V DC/200mA ISOLATED FROM THE MAIN VOLTAGE (isolated winding or another transformer). Dimensions : 78 x 90 x 29 mm 2
