ems4.DEA2I
CAN Field Bus Fire Damper Module for Safety Ring Bus System
The module is used for direct connection of a motorised fire damper with feedback signals. The module is suitable for both 230V and 24V actuators. It enables the fire damper to be closed on a test basis via the system bus with simultaneous monitoring of the end positions. The direct connection of the fire damper actuator (voltage and feedback) is performed via standardised connection plugs on top of the connection terminals. An external thermoelectric tripping device is provided for connection. Due to its dual communication interface, the DEA2I is suitable for use in a highly available ring bus system. This ensures continued communication in the event of a fault in the bus system, e.g. due to a short circuit or interruption. Thanks to its installation housing, the module is suitable for direct mounting in the immediate vicinity of the fire damper.
