Product Description

The ST17H intelligent temperature transmitter provides an economical solution for temperature detection applications. The ST17H 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:
• HART/4-20mA output
• Thermal resistance,thermocouple, resistance value or millivolt input
• Single or dual sensor (difference or average) input
• Type B DIN rail or head mount
• It can be connected with HART multipoint mode
• Sensor fault signals comply with NAMUR NE43
• It is configured using the STT17C configuration tool and PC or HART field configuration
• Electrical isolation


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