Improve access to your HART process data with our innovative products for continuous access.
For the past 25 years, HART devices have been installed globally in countless applications related to flow, pressure, temperature, and level measurement. In many cases, only the 4 to 20 mA signal is permanently connected, while the HART data is only accessed during startup and troubleshooting.
HART components from Phoenix Contact provide a cost-effective, permanent connection to all your HART data, thereby optimizing maintenance and system operating times.
Signal isolators from Phoenix Contact provide access to the digital HART signal. The devices can be installed in both regular and ATEX environments. Signal isolation, combined with the provision of the power supply loop to the field device, ensure a more secure and easily accessible installation.
Our product range offers numerous advantages and is being continuously further developed to enable us to respond to your application requirements.
Protection of the 4 to 20 mA loop and the digital HART signal is a basic prerequisite in many applications where there is a considerable distance between the controller and the device. The pluggable surge protection solutions from Phoenix Contact provide reliable protection and consistent signal power.
The pluggable and coded solution ensures an uninterrupted connection, even during the plug-in process.
Depending on the application, serial RS-485 or Ethernet-based access to all the digital data is possible from HART devices.
Conventional serial RS-485 multiplexers can be used for applications that are not time-critical. Each multiplexer enables up to 32 devices to be connected. Data exchange is on a serial basis, as communication takes place via just one HART master.
The Ethernet HART multiplexer provides PROFINET, Modbus TCP/IP, and HART-IP access to 40 devices, each with their own HART master connection, for time-critical applications.
When using a Modbus TCP/IP network, it is also possible to provide four digital inputs and four digital outputs.
