Product Description
PR Electronics 3112 Temperature Converter delivers precise and reliable temperature input signal conversion with a maximum supply voltage of 31.2V dc and operating temperature range from -25°C to 70°C. This temperature converter is part of the 3000 series known for compact size, fast response, and exceptional EMC immunity, making it well-suited for industrial automation and process control applications.
The device supports versatile output types including analogue voltage (0/1 to 5 V, 0/2 to 10 V) and current outputs (0/4 to 20 mA), ensuring compatibility with various PLCs and DCS systems. Featuring a high basic accuracy of 0.05% for all signal ranges, it maintains long-term precision with a low temperature coefficient better than 0.01% per °C, reducing the need for recalibration.
Fast response times under 30 milliseconds enable rapid process measurement updates, critical for monitoring and control in industrial, manufacturing, and HVAC environments. The robust galvanic isolation of 2.5 kVAC provides excellent noise immunity and protection against electrical interference, enhancing signal integrity.
Configuration is simplified via DIP-switch programming, allowing more than 1000 pre-calibrated temperature range settings without requiring device recalibration after range changes. For hazardous area applications, the 3112 model carries certifications including ATEX, IECEx, UL, FM, and others, suitable for Zone 2 and Division 2 installations.
The slim 115mm deep housing enables snap-on mounting to DIN rails, supporting vertical or horizontal installation without the need for air gap separation. This rugged design is ideal for outdoor panel integration, where wide ambient temperature variation occurs.
High 0.05% accuracy for signal ranges. Multiple output types: voltage and current analogue signals. Rapid temperature measurement response less than 30 ms. Safe galvanic isolation at 2.5 kVAC. DIP-switch for easy range configuration without recalibration.
Certification for hazardous locations including ATEX and IECEx. Durable operation from -25°C to 70°C ambient temperatures. Compact 115mm depth design for DIN rail mounting.
This temperature converter is extensively used in industrial automation, process control, manufacturing, HVAC systems, water treatment plants, and marine applications. Its compliance with multiple international standards ensures reliability and safety in critical measurement environments.
