EM-BAC-MOD Expansion Module BACnet

TROX EM-BAC-MOD Expansion Module BACnet EXPANSION MODULE BACNET MS/TP, MODBUS RTU BACNET-MS/TPSCHNITTSTELLE

MODBUS-SCHNITTSTELLE

EM-BAC-MOD
BACNET AND MODBUS INTERFACE FOR UNIVERSAL CONTROLLERS AND ADAPTER MODULES
Expansion module for UNIVERSAL fume cupboard controllers, room controllers, extract air controllers, supply air controllers, and adapter modules, for the integration of rooms or individual volume flow controllers with the central BMS

Switching between BACnet MS/TP and Modbus RTU
BACnet Standardised Device Profile (Annex L)
Modbus interface with individual data registers
Native BACnet interface by integrating the expansion module with EASYLAB components
Easy retrofitting
Double-stack terminal blocks for the EIA-485 bus
Equipment address and data transfer parameters can be defined

Interface to central BMS

When used on a controller with active room management function (RMF) the module provides also data points for the entire room, e.g. for total volume flows or consolidated alarms
When used on a single controller: data points for volume flow rate, alarm, damper blade position, or others
Centralised operating mode default setting, e.g. night-time operation

Application

Application

Expansion module Type EM-BAC-MOD for the EASYLAB system
BACnet-MS/TP or Modbus RTU interface to the central BMS
Data points for individual controllers or for the room
Room interface: Default setting of room operating modes within the EASYLAB system, increase or reduction of the air change rate, readout of the actual room operating values or evaluated damper blade positions, consolidated alarms
Controller interface: Operating mode default setting for a single fume cupboard controller, readout of individual operating values such as volume flow rates for single controllers, or individual alarms
Can be used with fume cupboard, supply air, extract air or differential pressure controller EASYLAB TCU3 and with adapter module TAM
For use in laboratories, clean rooms in the pharmaceutical and semiconductor industries, operating theatres, intensive care units, and offices with very demanding control requirements
Factory mounted or for retrofitting into the EASYLAB base component casing

Special characteristics

Ready for installation, can be easily connected to the main PCB
Interface for EIA-485 networks BACnet MS/TP and Modbus RTU
BACnet Protocol Revision 12.0
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
Hardware switch to enter network addresses and communication parameters (no communication software required)

Description

Parts and characteristics

Microprocessor with setup programme stored in nonvolatile memory
EIA-485 communication interface
Slide switch to switch between BACnet and Modbus communication protocols
Two address switches, X and Y, to set equipment addresses 1-99
8-way DIP switches to adjust the communication parameter
Double-stack terminal blocks for the EIA-485 network (simple wiring)
Two indicator lights indicate communication and errors, respectively
Connection to update the firmware
EIA-485 terminal resistor that can be activated

Construction features

PCB dimensions and fixing points correspond to the EASYLAB main PCB and the casing
Fixing with screws
Pin header to connect the module to the main PCB of the TCU3 or TAM
