Temperature Monitoring
SIO-RTD SERIES
Temperature Input Monitor
Description
The SIO-RTD is a microprocessor-based data-acquisition
system for measuring temperatures accurately with resistance
temperature detectors (RTDs) and for monitoring 4-20 mA
analog-output devices in industrial environments. RTD inputs
are noise-filtered and automatically calibrated for lead-length
compensation, ambient temperature, and other factors
providing accurate readings through the specified temperature
range for several types of RTD devices.
