PR 5131 2-wire Temperature Transmitter from PR electronics

Built for performance and safety, the PR 5131 2-wire Temperature Transmitter features 3.75 kVAC galvanic isolation, protecting sensitive control equipment from electrical noise and interference. As a result, the 5131 also enhances system reliability. Its jumper-selectable inputs allow independent channel configuration for temperature or current / voltage measurement, thus providing customization for specific process requirements. The transmitter supports automatic cable compensation (3- or 4-wire) and programmable cable resistance for 2-wire setups.

• Independent channel jumper selectable inputs for current / voltage or temperature. 
• Current input programmable in range 0-100 mA and voltage inputs in range 0-250 VDC.
• Linearized, electronic temperature measurement with RTD or TC sensor.
• Conversion of linear resistance variation to a standard analog current / voltage signal, for example, from solenoids and butterfly valves or linear movements with attached potentiometer.
• 4- or 3-wire connection automatic cable compensation or 2-wire connection with programmable cable compensation.
• Configurable sensor error detection including NAMUR NE43.

Easy Mounting, Installation, and Programming
