E-BUS Adapter Board  

ASM01878  

ALT-REF number OE365-15-EBA

 

Description

 

The E-BUS Adapter Board is used to provide a 
connection point for multiple E-BUS Sensors or 
Modules. 

The E-BUS Adapter Board is also used for 
connecting an EBTRON

®

 GTC116 or HTN104 

Airflow Measurement Digital Transmitter, a 
GreenTrol

 GA-200-N Transmitter Module with 

GF Series Airflow Monitoring Station, or Paragon 
MicroTrans

EQ

 series MODBUS RTU Transmitter 

to the VCCX2, VCB-X, VCM-X E-BUS, or various 
other AAON Unit Controllers.  

You must wire the EBTRON

®

, GreenTrol

TM

, or 

Paragon* Airflow Measurement Digital 
Transmitter to this Adapter Board.  

The E-BUS Adapter Board has (4) Modular E-
BUS ports, (3) HSSC E-BUS Connections, and (2) MSTP  
E-BUS Connections.  

Mounting

 

The E-BUS Adapter Board is provided with a plastic snap track modular mounting base. The snap track is 
designed to be mounted with the provided sheet metal screws to a flat surface. There is (1) pre-punched 
mounting slot provided.  The other screw may be drilled into the snap track to prevent rotation. The E-BUS 
Adapter Board is then snapped into place on the snap track to provide for easy field mounting and servicing.
