SIO-RTD-02-00

Protection Relays, Monitors & Systems 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. Features & Benefits BENEFITS 8 Inputs Single module can collect multiple data points CSA Class 1 Zone 2 Hazardous-location Certified Individually-selectable Input Type Simplified Circuit Diagram M Flexible; can be used with Pt100, Ni100, Ni120, Cu10 RTD or 4-20 mA inputs Conformal Coating Protects circuit boards against corrosion and moisture Remote Monitoring Up to 1.2 km away from network master Notch Filter Rejects noise from motor monitoring applications For detailed wiring diagram, see page 86.
