PR Electronics 3101, Temperature to Current Signal Conditioner,

The PR Electronics 3101 TC Converter is a high‑precision signal conditioning module designed for converting thermocouple (TC) inputs (types J and K) into a standard analogue output suitable for process control systems. Its slim-line 6.1 mm DIN-rail housing makes it ideal for high-density cabinet installations, while factory‑calibrated ranges via DIP‑switch ensure fast configuration and integration in industrial and hazardous‑area environments.

Unique Features and Benefits of the PR Electronics Temperature to Current Signal Conditioner

• Converts thermocouple J/K inputs to programmable 4‑20 mA (or 0‑20 mA) current output or 0‑1/0‑5 V / 0‑2/0‑10 V voltage output.
• Exceptional accuracy: better than 0.1 % of span across selected input ranges.
• Compact 6.1 mm wide housing allows up to 163 units per meter on standard DIN rail.
• Fast or damped response selectable: < 30 ms for rapid sensing or 300 ms when signal smoothing is preferred.
• High robustness to EMC/EMI disturbances, meeting NAMUR NE21, NE43 and suitable for Zone 2/Div 2 hazardous areas.
• Dedicated sensor‑error diagnostics and open‑thermocouple detection with configurable “out‐of‐range” output via DIP‑switch.
• Wide ambient temperature range (‑25 °C to +70 °C) and DIN rail mounting ease for industrial automation environments.

Built for Reliable Signal Conversion in Industrial Environments

Designed with a focus on accuracy, repeatability and ease of integration, the 3101 ensures reliable conversion of thermocouple signals into standard current or voltage outputs, even in electrically noisy or harsh plant conditions. The slim housing saves panel space while DIN‑rail mounting simplifies retrofits and upgrades. With factory‑calibrated ranges and DIP‑switch setup, commissioning time is minimised.

Broad Range Application

• Conversion of TC J or K temperature sensors to 4‑20 mA or 0‑10 V signals in automation cabinets.
• Instrumentation and control panels in water/wastewater, HVAC and manufacturing industries.
• Hazardous area installations (Zone 2 / Division 2) where thermocouple inputs must be safely conditioned.
• Skid‑mounted or field‑mounted systems requiring compact DIN rail modules.
• OEM panels where high channel density and minimal footprint are required.
• Retrofitting existing analogue control loops with new thermocouple input capabilities.
