Product Description

The D304U isolator, also recognized as the 3M GNAE isolator, is a robust signal isolator engineered for industrial automation and process control. It supports 1 analog input and 1 analog output, directly interfacing with PLCs, sensors, and transmitters via 4-20mA or 0-10V signals. Operating within a 12-24V DC voltage range and -20°C to +70°C temperature limits, it ensures reliable performance in harsh environments such as oil/gas, chemical, and power industries. The device features galvanic isolation, eliminating ground loops and enhancing noise immunity. Key advantages include high accuracy (±0.1%), fast response (<50ms), and compact DIN-rail mounting. While lacking wireless connectivity, its RS-485 communication port enables Modbus protocol integration. With IP20 protection and no onboard display, it prioritizes functional durability over user interface. The isolator delivers a detection range up to 500 meters for current signals, making it suitable for long-distance signal conditioning.
