STT173 Intelligent temperature transmitter
Analog output 4~20mA
Product Description:
The STT173 intelligent temperature transmitter provides an economical solution for temperature detection applications. The STT173 is more accurate, safe and reliable than the directly connected temperature measuring points, while reducing the wiring cost. The temperature signal output of this temperature transmitter is automatically linearized within the upper and lower limits set by the user. In addition, users can program high - and low-limit alarm points and make them alarm if the sensor fails.
Product features:
Analog output 4~20mA
Sensor fault signals comply with NAMUR NE43
Use STT17C configuration tool and PC to configure it
Thermal resistance, thermocouple, resistance value or millivolt input
Type B DIN rail or head mount
Electrical isolation
