GENERAL
Wide Area Communication Router (WAC Router) is
the hardware equipment to connect Vnet/IP domains
via Wide Area Network (WAN). Operations and
monitoring of the FCS/SCS that are distributed
in remote areas can be realized. Satellite
communications can also be used as a WAN.
HARDWARE SPECIFICATIONS
About the installation and environmental conditions of
the WAC Router, refer to “Integrated Production Control
System CENTUM VP System Overview (Vnet/IP
Edition) (GS 33K01A10-50E),” which is common with
the WAC Router.

Communication specifications
Vnet/IP Communication Interface (*1):
Dual-Redundant
WAN Communication Interface:
Single or Duplexed (100BASE-TX)
*1:
For more details, refer to “Integrated Production
Control System CENTUM VP System Overview
(Vnet/IP Edition)” (GS 33K01A10-50E).
The high performance diff erential pressure transmitter
EJA110E features single crystal silicon resonant
sensor and is suitable to measure liquid, gas, or
steam fl ow as well as liquid level, density and
pressure. EJA110E outputs a 4 to 20 mA DC signal
corresponding to the measured diff erential pressure.
Its accurate and stable sensor can also measure the
static pressure which can be shown on the integral
indicator or remotely monitored via BRAIN or HART
communications. Other key features include quick
response, remote set-up using communications and
self-diagnostics. FOUNDATION Fieldbus, PROFIBUS
PA and 1 to 5 V DC with HART (Low Power) protocol
types are also available. EJA-E series models in
their standard confi guration, with the exception of
the Fieldbus, PROFIBUS and Low Power types,
are certifi ed as complying with SIL 2 for safety
requirement.
