Reader - SmartRelay 3 system

At least one external reader is required to use the SREL3 ADV system. SmartRelay 3 readers are ordered separately from the controller.

The controller is unable to read identification media. Up to three readers can be connected via an RS-485 interface for this purpose. They can read both active and passive identification media. After reading media, the readers transmit the data to the controller, which checks the identification medium's authorisation and triggers relevant actions as programmed. The reader itself is unable to trigger actions and can thus be installed in less protected areas. In the WP variant, the housing is sealed and protected against splashing water.

Readers can either be powered through the controller or equipped with their own power supply unit.

NOTE

Too low operating voltage

When selecting the power supply, please allow for a voltage drop occurring in conductors. A voltage drop can cause the operating voltage in the reader to fall below the required level and malfunctions may occur. In such a case, either the operating voltage on the controller needs to be increased or the reader equipped with its own power supply unit.

A multi-coloured LED signals the different operating modes.
