Linearized 3-Wire RTD Input, Analog-Sensor-to-Digital Signal Conditioner
PRELIMINARY
Description
10D-RTD3 linearized temperature input modules are designed to interface with 3-wire Pt100 sensors used in industrial, test, and measurement applications.
Each module provides a single channel of temperature input that is filtered, isolated, amplified, and converted into 24-bit digital data for precise measurement of temperature signals.
RTD excitation is provided by the module using a precision current source. Excitation current does not flow in the input signal leads, which allows RTD measurements to be made independently of lead resistance. Low excitation current (250μA) minimizes self-heating of the RTD, further reducing measurement errors.
Discrete output pins can be mapped to configurable low and high alarms to provide essential monitoring and warning functions to ensure optimum process flow and fail-safe operation.
Input-to-digital isolation is rated at a robust 1500Vrms and all field-side inputs are protected against accidental power-line connections up to 240Vrms. These features safeguard measurement and control equipment from the harmful effects of signal noise, transient surges, ground loops, and other industrial hazards.
Over-range and under-range up to 10% beyond specified input values are supported with accuracy guaranteed to ±full-scale. All 10D modules are housed in rugged thermoplastic packages and are specified to operate over the industrial temperature range of –40°C to +85°C.
