Product Description

The PR3545 Isolator, also known as the 3545 Transmitter Module, is a high-precision RTD Signal Conditioner 3545 designed for industrial automation and process control. It supports dual RTD input channels and delivers a single isolated 4-20mA output, enabling direct integration with control systems. Operating within a voltage range of 12-30V DC, it functions reliably across a temperature span of -20°C to +70°C. This module features galvanic isolation to prevent signal interference and is compatible with standard 2-wire or 3-wire RTD sensors, ensuring accurate temperature measurement. Its rugged construction suits harsh environments, including oil/gas, chemical, and manufacturing sectors. While lacking a built-in display or communication ports like HART/RS-485, it excels in simplicity and reliability. Typical signal transmission spans up to 100 meters, with no battery dependency due to external power sourcing. Compact and DIN-rail mountable, it optimizes space efficiency in control panels.
