Eltako Shutter actuator RS485 bus actuator for shading elements and roller shutters

Switch actuator for shading elements and roller shutters with 2 channels for two 230V motors. 2+2 normally open contacts 4A/250V AC, isolated from the supply voltage of 12V. Bidirectional. Standby loss is only 0.1 watts. Rail-mounted device for installation on a mounting rail. Connection to the Eltako RS485 bus. Cross-wiring of bus and power supply with a jumper. Contact switching at zero crossing to protect the contacts and motors. One motor is connected to terminals 1, 2, and N, while a second motor can be connected to terminals 3, 4, and N. When both relays of the FSB14 are activated, 0.4 watts are required. In the event of a power failure, it is defined to be switched off. The buttons can be programmed either as direction buttons or as universal buttons: Local control with a universal button: With each pulse, the switching position changes in the sequence of Up, Stop, Down, Stop. Local control with direction buttons: A pulse at the top specifically activates the Up position. A pulse at the bottom specifically activates the Down position. Another pulse in the same direction immediately interrupts the process. However, a pulse in the opposite direction will stop the process and switch to the opposite direction after a pause of 500 ms. Central control dynamic without priority: With a control signal from a button programmed as a central control button without priority, the Up position at the top or Down position at the bottom is specifically activated. Without priority, because this function can be overridden by other control signals. Central control dynamic with priority: With a control signal of at least 2 seconds from a button programmed as a central control button with priority, the Up position at the top and Down position at the bottom is specifically activated.
