Pt100/Pt1000線性化J、K和S型熱電偶帶線性化只能使用電氣隔離傳感器。+5 V的范圍也適用于測量0…20 mA，如果使用250的外部分流器。輸入通道的配置以及模塊地址的設(shè)置在DIL中執(zhí)行開關(guān)。
ICDT 08 B5模塊在字中使用一個(gè)地址輸入范圍為0…6。8個(gè)通道中的每個(gè)通道都需要16位。
該模塊由24 V DC供電。CS31系統(tǒng)母線連接與其余部分電氣隔離模塊組件。

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.
