Product Description

The ST173 intelligent temperature transmitter provides an economical solution for temperature detection applications. The ST173 is more accurate, safe and reliable, and reduces the cost of wiring compared to the directly connected temperature measuring points. 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.


Characteristics:

• 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

Applications:
• Support PT100/PT1000 thermal resistance
• 8 kinds of thermocouples
