CI852和TP852–基金会现场总线H1接口
主要特征
•一个基金会现场总线端口提供
通信速度为31.25 kbit/s（FF H1）
•变压器隔离
•FF H1总线无功耗
•未向FF H1总线供电
•简单的DIN导轨安装
•预设，两个字母的Alpha代码锁，见上表4
75页，安装在装置底座中，以防止不正确
不兼容部件的安装。
描述
CI852连接基金会现场总线H1
（FF H1）至AC 800M。FF H1具有
通信速度为31.25 kbit/s，用于：
现场仪表的远程连接。CI852是
通过变压器连接到总线，因此
既不供应也不消耗总线电力。
可连接的现场仪表数量
通过CI852取决于FF H1网络的物理限制
具有任何软件限制（请参阅软件文档）。
FF H1总线允许重复使用现有电缆，用于：
4-20mA模拟信号。这意味着电缆往往成为主导
尺寸因子。FF配置工具可直接连接至FF
H1总线。
CI852已被CI860通信接口（连同
LD800HSE连接装置）。CI852仅出于传统原因进行描述。

CI852 and TP852 – FOUNDATION Fieldbus H1 Interface Appendix A Hardware Units
288 3BSE036351-510 A
CI852 and TP852 – FOUNDATION Fieldbus H1 Interface
Key Features
• One FOUNDATION Fieldbus port provides a
communication speed of 31.25 kbit/s (FF H1)
• Transformer isolated
• No power consumed from the FF H1 bus
• No power is supplied to the FF H1 bus
• Simple DIN-rail mounting
• Pre-set, two letter Alpha code lock, see Table 4 on
page 75, installed in unit base to prevent incorrect
mounting of non-compatible components.
Description
The CI852, connects the FOUNDATION Fieldbus H1
(FF H1) to the AC 800M. The FF H1 has a
communication speed of 31.25 kbit/s and is intended for
remote connection of field instruments. The CI852 is
connected to the bus via a transformer, and as such
neither supplies nor consumes bus electrical power.
The number of field instruments that can be connected
via the CI852 depends on the physical limitations of the FF H1 network, together
with any software limitations (refer to the software documentation).
The FF H1 bus allows reuse of existing cabling for
4-20 mA analog signals. This means the cables often become the dominant
dimensioning factor. An FF configuration tool can be connected directly to the FF
H1 bus.
CI852 has been replaced by the CI860 communication interface (together with
the LD800HSE linking device). CI852 is only described for legacy reasons.
