Veris E8950 Datasheet
E8950
Modbus-to-BACnet
Protocol Converter
VERIS INDUSTRIES
Integrate Multiple Modbus
Meters into a BACnet Network
DESCRIPTION
E8950 Modbus-to-BACnet Protocol Converter enables easy integration of a broad
selection of Veris meters with Building Automation Systems via BACnet protocol.
When networked, the E8950 detects supported Modbus meters and gives them
a unique BACnet Device ID and full set of measurement data and conguration
objects. Simply select the desired MS/TP baud rate using DIP switches or congure
the IP interface using the integral web server, and the supported Veris Modbus
meters are available as fully-supported BACnet devices.
APPLICATIONS
● Energy Management with Building Automation Systems
● Integrated metering of HVAC systems and chillers
network integration
E8950
FEATURES
● Enables Veris meter access via BACnet MS/TP and/or BACnet IP...compatible
with standard building protocols
● Supports a broad range of Veris meters: H8035, H8036, H8163 with H8163-
CB, H8238, H8436, H8437, E50C2, E51C2, E50C3*, E51C3*, E30Ax42, E30Bxxx,
E30Cxxx, E31Bxxx, E31Cxxx...application exibility
● Each E8950 can support up to 1000 BACnet measurement points (or 32 meters
max., if <1000 total points)...extensive data collection
● Simultaneously suppor ts mixed meter types (with common baud rate)...
versatility in the eld
● Simple to set up...automatically detects suppor ted meters and congures
BACnet objects...no manual mapping of Modbus points required
● Presents a separate device object for each meter attached...easy to program
● Can be mounted on DIN rail or wall...installation exibility
* The logging func tionality of these meters is not suppor ted.
