EM-IP

Expansion module to supplement an EASYLAB base component (controller TCU3 or adapter module TAM) with a BACnet/IP or Modbus/IP interface to link rooms or individual volume flow controllers to the central BMS.

Expansion module includes an interface for IP-based networks; switching between BACnet/IP and Modbus/IP is possible. All settings for alarming, trend logging, event logging, notifications and scheduling can be accessed and changed using the integral webserver.

Special characteristics

• Ready for installation, can be easily connected to the main PCB
• Interface for IP-based networks BACnet/IP and Modbus/IP
• BACnet Application Specific Controller (B-ASC) according to Annex L
• Connection for access to BACnet/IP network, Modbus/IP network or integral webserver
• BACnet/IP Protocol Revision 7.0
• Only standard BACnet objects or Modbus registers are used for communication
• Data interface for an EASYLAB controller or for an EASYLAB room with different functional profiles
• Multi functional Reset push button
• All settings for alarming, trend logging, event logging, notifications and scheduling can be accessed and changed using the integral webserver (no configuration software required)
• 2 GB microSD card for firmware, trend logging, event logging and alarming
• With BACnet Broadcast Managment Device (BBMD) function
• Foreign devices are supported
• Firmware is updated using the webserver

Data points for a single controller

• Volume flow rate actual and setpoint values
• Damper blade position
• Operating mode
• Alarm/status messages
• Total supply air and total extract air actual values (room), and all individual volume flow rate values
• Evaluated damper blade positions for all controllers in a room
• Number of controllers
• Integration of volume flows

Additional data points for a fume cupboard controller

• Operating mode default setting for the fume cupboard controller equipped with the expansion module
• Selection of priority for operating mode default setting
• Face velocity actual value and setpoint value (only for fume cupboard controllers with face velocity transducer, equipment function FH-VS)

Data points for an EASYLAB room

• Operating mode default setting for the room: Just one data point is required to set the default operating mode for all controllers in a room
• Selection of priority for operating mode default setting (central BMS or room)
• Room operating mode
• Volume flow rate setpoint change (by the central BMS, for example) for an external temperature or differential pressure control
• Setpoint value switching for differential pressure control: Switching between two differential pressure setpoint values
• Total supply air and total extract air actual values (room), and all individual volume flow rate values
• Evaluated damper blade positions for all controllers in a room
• Room differential pressure actual and setpoint values
• Room pressure alarm
• Number of controllers within the EASYLAB system
• Integration of volume flows
• Status of the digital inputs and outputs
• Configurable consolidated alarm (operating statuses, hardware faults)
