BASremote Master — Versatile Web Appliance
The BASremote Master provides the ultimate in
flexibility. It can be used for expansion I/O at remote
locations where an Ethernet connection exists. Its
built-in router and gateway capabilities address
unique integration needs where more than one
communications protocol is involved. It can operate
as a function block programmable controller with its
resident Sedona Framework Virtual Machine. Powered
by a Linux engine, the BASremote Master can operate
as BACnet/IP and Modbus TCP remote I/O, Sedona
Framework controller, Modbus Serial to Modbus TCP
router, Modbus Serial to BACnet gateway, and Modbus
master to attached Modbus slaves all at the same time.
A 10/100 Mbps Ethernet port allows connection to IP
networks and popular building automation protocols
such as Modbus TCP, BACnet/IP, and Sedona SOX.
Six universal I/O points and two relay outputs can
be configured through resident web pages using
a standard web browser and without the need of a
special programming tool. A 2-wire Modbus serial port
can greatly expand the I/O count with built-in routing to
Modbus TCP clients. If BACnet mapping is preferred,
the unit incorporates a Modbus serial to BACnet/IP
gateway. The BASremote Master also allows you to
install custom web pages so you can view the status of
your system in a convenient manner.
Additional universal I/O can be achieved with the simple
addition of BASremote Expansion modules. The
BASremote PoE has the same capabilities as the
BASremote Master except it is powered over the Ethernet
connection thereby providing a “One Cable Solution”.
Universal I/O
Using web pages, six points can be configured as either inputs or outputs, analog or digital. In addition to being discoverable as
BACnet objects, these same points can be assigned Modbus addresses.
• Analog inputs: 0–10 VDC, 0–20 mA but scalable to 0–5 VDC and 4–20 mA
• Temperature inputs: Type II or Type III thermistors
• Contact closure or Pulse inputs: Free-voltage, 40 Hz maximum
• Analog outputs: 0–10 VDC, 0–20 mA
All field connectors are removable.
