OneWire Interface for 4-Wire RTD

The new RTD Sensor line offers an innovative and highly accurate way to monitor and control temperature throughout a wider temperature range than previously possible with 1-Wire networks. Each variation of the RTD sensor line includes a highly accurate RTD input, a LED, conditional search support and a pass-through 1-Wire connection. These features combine to offer a flexible system for monitoring and controlling numerous data points throughout a 1-Wire network in an efficient manner. The conditional search support allows a host adapter to quickly identify whether alarm for numerous parameters have been met. The LED are configurable to behave in a variety of ways when alarms:

Activates when an alarm becomes active and deactivates when the alarm is cleared
Activates when within alarm parameters and deactivates when in normal range
Independently controlled

The RTD sensor line has been designed to simplify the reading and controlling process. Any general purpose 1-Wire host adapter is able to read the RTD Sensors.

Selecting a RTD
