预期用途模拟输入模块ICDT 08 B5是一个远程模块在CS31系统总线上。它有8个模拟输入通道具有以下功能：通道成对配置，用于以下温度或电压的连接
传感器：+10伏/+5伏/+500毫伏/+50毫伏4…20 mA（带外部250分流器）
Pt100/Pt1000线性化J、K和S型热电偶带线性化只能使用电气隔离传感器。+5 V的范围也适用于测量0…20 mA，如果使用250的外部分流器。输入通道的配置以及模块地址的设置在DIL中执行开关。
ICDT 08 B5模块在字中使用一个地址输入范围为0…6。8个通道中的每个通道都需要16位。
该模块由24 V DC供电。CS31系统母线连接与其余部分电气隔离模块组件。
该模块提供多种诊断功能（请参见“诊断和显示”一章）。自校准是由模块内部控制循环执行环行显示器和操作元件前面板1 8个绿色LED用于通道选择和诊断，8个绿色LED用于粗略显示模拟频道

Intended purpose
The analog input module ICDT 08 B5 is a remote module
on the CS31 system bus. It has 8 analog input channels
with the following features:
The channels are configured in pairs for the
connection of the following temperature or voltage
sensors:
+ 10 V / + 5 V / + 500 mV / + 50 mV
4...20 mA (with an external 250 shunt)
Pt100 / Pt1000 with linearization
Thermocouples of types J, K and S
with linearization
Only electrically isolated sensors may be used.
The range of + 5 V is also suitable for measuring
0...20 mA, if an external shunt of 250 is use The configuration of the input channels as well as the
setting of the module address are performed at DIL
switches.
The ICDT 08 B5 module uses one address in the word
input range of 0...6. Each of the 8 channels needs 16 bits.
The module is supplied with 24 V DC. The CS31 system
bus connection is electrically isolated from the remaining
module components.
The module offers a number of diagnosis functions (see
chapter ”Diagnosis and displays”). A self–calibration is
carried out cyclically by the module’s internal control
circuit.

Electrical connection
The module is mounted on a 15-mm-high DIN rail or
fastened with 4 screws. The following figure shows the
electrical connection of the analog input module.The terminals of all temperature and voltage sensors have to
be electrically isolated from their mounting environment. The
cable shields of the sensor cables are connected to the switchgear
cabinet earthing when the cables enter the switchgear cabinet.
The configuration of the input channels as well as the setting of the
module address are performed at DIL switches (see next page).All input signals are evaluated as differential signals. The
sensor signals are connected double–pole to the inputs
U+ and U– (for examples see Fig. 5.2.5–2). The
relationship between the input signals and the output
numerical values is shown in the figures 5.2.5–7 to
5.2.5–9. All unused channels have to be short–circuited
(see also the termination of unused inputs configured as
Pt100/Pt1000 channels).
+ 10 V / + 5 V / + 500 mV / + 50 mV
The set measuring range is converted into the numerical
number range without linearization in the following way:
Analog representation a: –4095 ... 0.... +4095
Analog representation b: –32760 ... 0....+32760
If input voltages overflow the measuring range, the
overflow number of +32767 is output. If the input voltage
underflows the measuring range, the underflow number
of –32767 is output. In both cases, an error message is
sent via the CS31 system bus.
All unused channels have to be short–circuited.
