Intelligent Electronic Temperature Switch with Display

The temperature switch STS is robustly designed and easy to use. The STS is suited for temperature monitoring, measurement and control, such as used in cleaning liquid, hydraulic oil, heat-carrying agent and lubricant etc. It is temperature switch, transmitter and display in one and the same device. In its standard configuration it has two switching outputs (PNP or NPN). In addition, there are configurations available with an analog output signal (0…20mA| 420 mA or 0…5V| 010 V) as well as with RS485 Link.
