概述
SIRIUS 3RS1440 digital monitoring relay for 1 sensor
The 3RS14 and 3RS15 temperature monitoring relays for IO-Link
are used to measure temperatures in solid, liquid and gas
media. The temperature is calculated using a sensor in the
培养基，通过设备评估并监测过度旋
ing or undershooting a working range (window function).
The digital temperature monitoring relays have two separately
可调限制值,非易失性,可以be operated as
desired using the open- or closed-circuit principle.
The devices differ in terms of the number of temperature sensors
可以评估。IO-Link的3RS1440和3RS1540
temperature monitoring relays can be digitally adjusted for one
sensor and represent an alternative to temperature controllers in
the low-end range (two-point or three-point control).
例如，具有两点控制的设备可以用作
a thermostat. The devices with three-point control can, for exam-
ple，在加热和冷却之间独立切换。
IO-Link的3RS1441温度监测继电器可以是
digitally adjusted to evaluate up to three resistance sensors at
一度。这些设备专门设计用于监视
motor windings and positions.
温度监测继电器通过
control supply voltages IO-Link (L+) and ground (L-) or via an
外部24 V DC电源。
Monitoring
When the temperature has reached the
1 limit value, the K1
output relay changes its switching state after the configured
时间
t
has expired (output relay K2 reacts accordingly at
2).
The delay time can be adjusted.
输出继电器一次立即返回其原始状态
the temperature reaches the respective hysteresis value.
当温度达到顶部时
1 limit value, the K1
输出继电器在配置时间之后更改其切换状态
t
has expired. The output relay returns immediately to its original
state once the temperature reaches the respective hysteresis
价值。
The K2 output relay reacts in the same way at the
2 lower
临界点。两者都限制值
1和
2 can be parameterized for
过度弹出或触及阈值。这使它变得如此
possible to use a limit value for issuing an alarm signal to an-
nounce that a limit value is about to be overshot or undershot.
笔记：
“温度监控模式”参数可用于
设置所需的监视类型（监视过度弹药
or undershooting or range monitoring).
