概述
SIRIUS 3RS analog temperature monitoring relays for 1 sensor
3RS10，3RS11模拟温度监测继电器可以是
used for measuring temperatures in solid, liquid and gas media.
温度由介质中的传感器检测到
uated by the device and monitored for overshoot or undershoot.
When the threshold values are reached, the output relay
根据参数化打开或关闭。

好处
•
All devices except for 24 V AC/DC feature electrical
分离
•
使用旋转电位计非常简单的操作
•
Adjustable hysteresis
•
Adjustable working principle for devices with 2 threshold
值
•
All versions with removable terminals
•
All versions with screw terminals, many versions alternatively
with spring-type terminals
■
Application
The analogically adjustable SIRIUS 3RS10, 3RS11 temperature
监视继电器几乎可以在任何应用程序中使用
温度overshoot or undershoot is not permitted, e.g. in the
监视设定温度限制和警报输出
