• Lead Wire Resistance: Up to 30 ohms per wire (compensated)

• Resolution: 15-bit

• Accuracy: Typical ±0.01% of span (varies by RTD type)

• Isolation: 2500 Vrms (Group isolation field-to-logic)

• Mounting: Modular 200 Series Baseplate

• Power Requirements: 24VDC (sourced from the baseplate)

• Dimensions: 10.4 cm x 10.2 cm x 4.5 cm

Features

• Universal RTD Support: Software-configurable to accept various RTD types and wiring configurations (2-wire, 3-wire, or 4-wire), providing maximum flexibility for field installations.

• Automatic Lead Compensation: Features internal circuitry to automatically compensate for lead wire resistance, ensuring that temperature readings remain accurate even over long cable distances.

• Redundant Capability: Supports redundant pairing when used with a redundant baseplate, providing high availability for critical temperature-sensitive control loops.

• Digital Filtering: Includes advanced noise rejection and digital filtering to eliminate interference from high-frequency electrical noise typical in industrial environments.

• Hot-Swappable: Designed for online module replacement, allowing for hardware maintenance without powering down the Field Control Processor (FCP) or impacting adjacent I/O.

• Sophisticated Self-Diagnostics: Continuously monitors for open RTD sensors, short circuits, and internal module calibration health, reporting faults immediately to the system operator.
