Phoenix Contact's new Ethernet HART multiplexer provides a simple way to parameterize and monitor field devices on an Ethernet network. The GW PL ETH/-… is an up-to-date replacement for the widely used RS-485 HART multiplexer solution. The new multiplexer lets users perform operations that save time and money—including loop checks, device calibration, and improved process monitoring with multivariable devices—with existing devices.

The multiplexer consists of a head station and a variety of HART expansion modules to suit any application need. The modular design allows up to five expansion modules to be connected to a single head station. The result is a scalable solution for modern, distributed control systems and phased roll-outs.

The multiplexer supports the recently released HART-IP protocol, the new standard for HART communication over Ethernet. This offers an easy-to-use, widely available interface to provide standardized deployment and the ability to do intelligent HART device management using Ethernet.

Designed for applications like partial-stroke testing, valve diagnostics, and batch-data transfers, the multiplexer features a HART master on each channel for the fastest possible updates and execution times. All of the modules are rated for use in Class I, Division 2 and Zone 2 hazardous locations and operate in -40 to 70 degrees Celsius temperature extremes.
