PR 3113 HART Temperature Converter

PR Electronics 3113 HART Temperature Converter is a high-performance, isolated temperature conversion module designed for demanding industrial measurement environments. This compact yet powerful HART temperature converter accurately transforms signals from standard Pt100 RTDs and J/K thermocouples into isolated analog current and HART 7 digital outputs, making the 3113, from PR electronics, ideal for integration with modern control systems.

• The PR 3113 HART temperature converter measures a standard Pt100, TC J and K temperature sensor and provides an isolated active analog current and HART signal output.
• High 3 port isolation provides surge suppression and protects the control system from transients and noise.
• The 3113 can mount in the safe area or in Zone 2 / Division 2 hazardous areas.
• Features approval for marine applications.

Built with exceptional precision, better than 0.05 % of span, the 3113 ensures reliable, repeatable temperature measurement critical to process control, quality assurance, and safety systems. Its selectable internal or external cold junction compensation and switchable response time (from a rapid 60 ms up to 60 s) provide flexibility across diverse applications.

Engineered with a slimline 6.1 mm housing, this HART temperature converter maximizes space efficiency on DIN rails, thus allowing up to 163 units per meter without gaps. Rugged galvanic isolation and robust EMC performance safeguard your system from electrical noise and transient surges, while compliance with NAMUR NE21 and NE43 standards supports stable operation even in harsh industrial environments.

• Flexibly powered by 24 VDC (±30%) via power rail or connectors.
• A 60 ms fast response time with simultaneous sensor error detection when selected.
• Selectable internal/external CJC.
• Excellent conversion accuracy in all available ranges, better than 0.05% of span.
• Meeting the NAMUR NE21 recommendations, the 3113 provides top measurement performance in harsh EMC environments.
• The device meets the NAMUR NE43 standard defining out of range and sensor error output values.
• A visible green LED indicates operational status of the unit and the input sensor.
• All terminals are protected against overvoltage and polarity error. 
• High galvanic isolation of 2.5 kVAC.
• Excellent signal/noise ratio of > 60 dB.
