产品描述

 

转换继电器 (型号TR122D和TR122DA)监测2路限制输入信号,TR122DA把测量到的温度/电阻值转换成一个成比例的直流电流。
TR122D(A)的应用如下:

用于机器和工厂的温度监测,带预警和报警功能。

控制温度,例如用于天然气管道加热或者工厂冷却。

用作Pt100(电阻式温度检测器)和电阻(仅TR122DA)的传感器。

功能概述

1个输入传感器, Pt100(电阻式温度检测器) 或者电阻

测量范围:-199...850°C / 0...850 分辨率:0,1 °C / 范围: -19,9...99,9 °C / 0-99,9

2个继电器输出: (每个有1个转换触点)

1个模拟量输出0/4-20 mA(可调比例)(仅TR122DA,与输入不可能分离)

通用电源AC/DC 24-240V

存储和显示测量的zui小值和zui大值
