The relay actuator is used to switch selected electrical devices. A variety of functions can be switched via four potential-free contacts. The sWave.NET wireless system and the sensor bridge connect the relay actuator simply and easily to the system. The sensor bridge serves as a central database for management of the relay status. As a standard feature it provides a REST-API via http(s) to establish the relay status and to request new status updates.
With the relay actuator, devices such as indicator lamps can be switched in typical Andon applications. Due to the extremely low power consumption of the actuators, the devices are also used in mobile AGV in order to extend the running times of these vehicles. For example, an AGV can be woken by a relay actuator from its deep sleep mode. At regular intervals (usually 1 minute) the relay receivers are sent the status information needed to activate an AGV via the wireless system.
