2.2 输入
Pt100 或 4-20mA 信号可按照装置的设计连接到 D1272AT
的输入上。
已控制输入的范围，如出现故障，会出现下列信号：
• 输入传感器故障或未连接
• 低于输入范围（低）
• 超过输入范围 （高）
4-20mA 输入可以使用 有源 或 无源 信号。
有源信号： 传感器 / 信号转换器已通电，不再需要外部任
何额外的电源（如
MTO/TT 油位显示器或 TT-PWM60 温度
传感器）。
无源信号： 传感器 / 信号转换器需要外部电源（如 MT-
ST160SK/TT
指针式温度计）。信号转换器电源可选择在
工厂通过接线端子
10 和 12 配置（见铭牌）。该电源可为
传感器
/ 信号转换器提供大约 24VDC 的电压。
2.3 最小 / 最大存储
末次重置后会存储下最小测量值和最大测量值。可用前
面的键调出这些值。见第
2.1 章
2.4 报警触头 ALM1 和 ALM2 ( 选择件 )
D1272AT 数字式显示器可选择配双继电器（见铭牌）。
2N/0 触头的转换点可设定不同的限定值并可以用于发出
报警信号或类似信号。超过设定限定值时，特别触头关
闭（报警
1 或报警 2 ），相应的状态 LED （ ALM1 和
ALM2 ）会闪烁。继电器连接在后面。见 4.3. 章。
限定值可按 2.1 章所述设定。
返回控制滋滞为 1K 。
2.2 Input
A Pt100 or 4-20mA signal can be connected to the input
of the D1272AT in accordance with the device design
(see nameplate).
The input range is monitored and, in case of error, the
followingmessages are output:
• The input sensor is defective or not
connected.
• The input range has been passed below
(Low).
• The input range has been exceeded
(High).
The 4-20mA input can be used with an
active or a
passive signal.
Active signal: The sensor/signal transducer is already
powered and does not require any additional power from
the outside (e.g., oil level indicator MT0/TT or
temperature transmitter TT-PWM60).
Passive signal: The sensor/signal transducer requires
external power (e.g., pointer thermometer MT-
ST160SK/TT). A signal transducer power supply can
be configured here optionally at the factory on terminals
10 and 12 (see nameplate). This power supply provides
a voltage of approx. 24 V DC for the sensor/signal
transducer.
2.3 Min- / Max-memory
The minimum measured value and the maximum
measured value since the last reset are stored. They
can be called with keys on the front. See chap. 2.1.
2.4 Alarm contacts ALM1 and ALM2 (optional)
The digital indicator D1272AT can be optionally
equipped with a double relay (see nameplate). The
switching points of the 2 N/O contacts can be set to
different limit values and can be used to generate an
alarm message or similar. When the set limit values
exceeded, the particular contact closes (alarm 1 or
alarm 2) and the related status LED (ALM1 and ALM2)
flashes. The relays are connected on the back. See
chap. 4.3.
The limit values can be set as described in chap. 2.1.
The return control hysteretic is 1K.

示器的最后定位为前面。然后轻按指示器使其靠着
控制板。检查确保控制板密封正确定位。
• 从后面开始，将支撑架滑过将置至其接触到控制板
的后面。支撑架上和下的支撑齿会卡进装置的支撑
格。支撑架的弹簧必须紧紧抵着控制板的后面。
装置安装好后就可以连接了。
4 电气连接
Proceed as follows to install the device:
• Slide the D1272AT digital indicator into the control
panel cutout so that the final location of the
indicator is in front. Then lightly press it against the
control panel. Check to make sure that the control
panel seal is positioned correctly.
• Starting from the back, slide the holder frame over
the device until it touches the back of the control
panel. The holder teeth on the top and bottom of the
holder frame will then snap into the holder grid of
the devices. The springs of the holder frame must
be pressed firmly against the back of the control
panel.
After the device has been installed, it can be connected.

For the connection of the D1272AT digital indicator, we
recommend using open cable shoes for M3 screw-type
connections. Follow the connection diagrams in the
appendix.
4.1 Voltage supply
The connection is performed via the connection
terminals 13 and14. Voltage: 90 - 264 V AC +1%, 50/60
Hz, max. of 7.5 VA.
4.2 Sensor input
When connecting the input signal, make sure that the
measuring ranges of the devices agree and adhere to
the maximum load of the circuit.
Pt100:
The Pt100 input is designed for the connection of a
Pt100 sensor with 3-conductor technology. The
connection is made via the terminals 1 and 2. The
equalizing line is connected to terminal 3.If a 2-
conductor sensor is to be connected, terminals 2 and 3
must be short-circuited. See figure 3.
4-20mA, active sensor:
When the 4-20mA sensor to be connected is active (i.e.,
no further outside voltage is needed), connect the
sensor to terminal 1 (-) and terminal 4 (+). See figure 4.

4-20mA,
无源传感器
D1272AT 数字式传感器配有驱动传感器 / 信号转换
器的模块时（见铭牌），无源传感器（如
MT-
ST160/TT 指针式温度仪）便可由此驱动。
传感器电源在接线端子 10 （ - ）和接线端子 12
（ + ）上约为 24VDC 。
传感器连接时，电压必须形成回路。为此，跳接接
线端子 1 和 10 并将输入传感器连接至接线端子 4 （ -
）和 12 （ + ）。见图 5 。
4.3 继电器输出报警 1 和报警 2 （选择件）
继电器输出设计为双继电器（即 2N/O 触头在接线端子 23
上有共同的势能）。
根据用途将继电器连接到接线端子 22 和 23 或 24 和 23 。
4.4 模拟输出（选择件）
模拟输出 ` 连接到接线端子 21 （ + ）和 19 （ - ）上。确
保连接装置的测量范围是相同的并与电路的最大载
荷相符。
4-20mA, passiver Sensor:
When the D1272AT digital indicator is equipped with a
module for powering a sensor/signal transducer (see
nameplate),a passive sensor (e.g., pointer thermometer
MT-ST160/TT) can be powered with this.
The sensor power of approx. 24 V DC is available on
terminal 10(-) and terminal 12 (+).
The voltage must be looped in when the sensor is
connected. For this, jumper terminals 1 and 10 and
connect the input sensor to terminals 4 (-) and 12 (+).
See figure 5.
4.3 Relay outputs alarm1 and alarm2 (optional)
The relay outputs are designed as double relay (i.e., the
two N/O contacts have a common potential on terminal
23).
Connect the relay to terminals 22 and 23 or 24 and 23
depending on your application.
4.4 Analog output (optional)
The analog output is connected to terminal 21 (+) and 19
(-). Make sure that the measuring range of the connected
devices isthe same and the maximum load of the circuit
is adhered to.
