Flexible, compact I/O

With the USB I/O module EB1E1A, a device of the product family Symphony MX is easily expanded with an input and a relay output (normally open contact) by simply connecting the EB1E1A to an available USB port of the device. As a result, an input for floating contacts (e.g. for use with a switch, button or relay output) and a floating, galvanically-isolated output contact is available immediately (e.g. for use with a door opener). The EB1E1A module can then be comfortably configured via the station’s web interface. The EB1E1A provides a secure, cost-efficient way of integrating inputs and outputs directly into the Intercom station. The resulting solution is suitable for implementing additional inputs and outputs for the control of external components. Thanks to latest PhotoMOS technology, the EB1E1A has a very long service life. In contrast to an electromechanical design, this relay output does not age – no matter how many switching cycles it has to handle. That is why the USB I/O module is excellent for operating permanently blinking lights or similar applications. This high flexibility and the ease of integration make the EB1E1A a cost-efficient solution wherever an output to switch loads is needed.
