PR Electronics 4500 Temperature Transmitter with Relay Output, 48V Supply, Operating Range -50°C to 85°C 5437A1

PR Electronics 5437A1 Temperature Transmitter is a high-performance industrial temperature transmitter designed for demanding applications. It converts a wide range of sensor inputs, including thermocouples and RTDs, into a reliable 4 - 20 mA output signal with relay output capabilities.

The transmitter supports input temperature ranges from as low as -200°C to a maximum of 850°C, enabling versatile use in various processes. It is designed to operate efficiently within ambient temperatures ranging from -50°C to 85°C.

Crafted for hazardous environments, this transmitter carries an ATEX Zone 2 certification, making it suitable for installation in explosive atmospheres (Zone 2 and Zone 22 / Class I, Division 1, Groups A, B, C, D). This enhances safety and compliance in industrial settings.

Communication flexibility is achieved through support for HART 5 and HART 7 protocols. Sensor inputs are highly versatile, including two, three, or four-wire RTDs and linear resistance up to 100 kΩ, with sensor redundancy functionality to maintain process availability and safety during sensor faults.

The innovative design allows wiring from both inside and outside the terminals and includes loop test pins for easy current measurements without breaking loop integrity. Onboard LEDs provide visual status notifications according to NAMUR NE44 and NE107 guidelines to assist in quick diagnostics.

The compact housing size of 44mm diameter and 20.2mm depth allows easy mounting on various probe diameters through a 1/4-inch center hole. Jumper pins facilitate write protection and transmitter burnout options, ensuring customizable configuration and protection.

This temperature transmitter is ideal for industrial, automation, HVAC, and process control applications requiring accurate, reliable temperature monitoring, and control. It is manufactured in Denmark, assuring high-quality standards and compliance.
