PT100 Electronic Digital Temperature Switch With PNP + 4~20mA +
Modbus Output
STS supports functions of switch delay, normally open, normally
closed, switching point settable, display temperature peak value
and environment temperature and other functions. It can connect
with PT100 and PT1000 temperature sensors.
The temperature switch STS is robustly designed and very 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 optional two switching outputs (PNP or NPN),
an analog output signal (0...20mA| 4…20 mA or 0...5V| 0…10 V) as
well as with RS485 Link.
