1： 1传统和HART I/O卡的冗余：
DeltaV冗余I/O使用与以下相同的2系列I/O卡：
非冗余I/O。这允许您利用您的投资
在已安装的I/O和I/O备件中。无其他配置
在使用冗余信道时需要。多余的
接线板提供相同的现场接线连接
作为单纯形块，因此不需要额外布线。
冗余自动感知：DeltaV自动感知冗余I/O，
这大大简化了向
系统冗余卡对被视为一张卡
在系统工具中。
自动切换：如果主I/O卡发生故障，
系统自动切换到“备用”卡
而无需用户干预。操作员得到了明确的指示

Increases productivity
Real-time, online equipment additions: Online addition
of new I/O interfaces means your process does not get
interrupted. As new equipment is added, the DeltaV Explorer
acknowledges it and assigns it basic configuration.
Increases process availability
1:1 Redundancy for Traditional and HART I/O cards:
DeltaV redundant I/O uses the same Series 2 I/O cards as
non- redundant I/O. This allows you to leverage your investment
in installed I/O and in I/O spares. No additional configuration
is needed when using a redundant channel. The redundant
terminal blocks provide the same field wiring connections
as simplex blocks, so there is no extra wiring needed.
Autosense of redundancy: DeltaV autosenses redundant I/O,
which greatly simplifies the task of adding redundancy to the
system. The redundant pair of cards is treated as one card
in the system tools.
Automatic Switchover: Should a primary I/O card fail,
the system automatically switches to the “standby” card
without user intervention. The operator is given clear
notification of a switchover at the operator display.

Product Description
The Traditional I/O subsystem includes:
„ I/O interface carrier (a DIN rail surface mounted)
on which all I/O related components are installed.
„ Bulk AC to 24V DC power supply for field devices.
„ An I/O interface consisting of an I/O card and an
I/O terminal block.
„ A variety of analog and discrete I/O cards enclosed
in a common form factor that easily plugs into the
I/O interface carrier.
„ A variety of I/O terminal blocks mounted on the I/O interface
carrier that can be pre-wired before I/O card installation.
I/O Cards
A variety of analog and discrete I/O cards are available to meet
your specific requirements. The following cards support simplex
or redundant installation:
„ AI 4-20 mA HART 8 channels
„ AO-4-20 mA HART 8 channels
„ DI, 24V DC Dry Contact, 8 channels
„ DO 24V DC High-Side, 8 channels
A Traditional I/O card easily plugs into an I/O carrier.
„ AI (Plus) 4-20 mA HART, 16 channels
„ AO (Plus) 4-20 mA HART, 16 channels
„ DI (Plus) 24V DC, Dry Contact, 32 channels
„ DO (Plus) 24V DC, High-Side, 32 channels
The following I/O cards are supported in simplex format
to meet your field wiring needs.
„ AI Isolated, 4 channels
„ RTD, 8-channels
„ Thermocouple, 8 channels
„ Millivolt, 8 channels
„ DI, High Density, 32 channels

All I/O cards are enclosed in a common form factor that plugs
into the I/O interface carrier. The housing is clearly labeled with
the enclosed I/O card type. All cards have power and internal
error indicators. Eight-channel cards have clearly visible channel
status LEDs.
All cards meet ISA G3 corrosion specifications by the careful
selection of superior electronic components and the use of
conformal coating.
