HART Modem with USB Interface

This HART modem with USB interface connects to a PC via USB and to the transmitter output via a load resisitor of between 200 and 500 ohms. See the diagram for connection. Software can be downloaded from our website to cconfigure and calibrate the transmitter.

This HART modem is used in conjunction with HART transmitters such as the HMT-648

The HART protocol, standing for Highway Addressable Remote Transducer, is a widely recognized communication standard in industrial automation. It offers several advantages that make it a preferred choice for many applications. Here are some of the key benefits:

Digital and Analog Capability: HART protocol uniquely combines digital communication with traditional 4-20 mA analog signaling. This dual capability allows for the transmission of digital information over the same wires as the analog signals, which are still used for controlling the process1.

Interoperability: One of the most significant advantages of the HART protocol is its interoperability. Devices from different manufacturers can communicate with each other, making it easier to integrate various types of equipment within a system1.

Availability: With over 30 million devices installed worldwide, the HART protocol’s widespread adoption ensures that compatible devices and sensors are readily available1.

System Availability and Productivity: The protocol helps increase system availability and asset productivity by providing early warnings against variances in device, product, or process performance2.

Maintenance and Troubleshooting: HART protocol can speed up troubleshooting, reducing the time taken between the identification and resolution of problems. This leads to lower maintenance costs and improved regulatory compliance2.

Legacy System Compatibility: HART protocol can be used over existing 4-20 mA systems without the need for new wiring, making it an excellent transition protocol for users who want to upgrade to smart technology while maintaining their legacy systems3.

In summary, the HART protocol’s ability to support both digital and analog communication, its interoperability among diverse devices, and its compatibility with legacy systems make it a robust and versatile choice for industrial automation. These features contribute to enhanced system reliability, reduced maintenance costs, and improved operational efficiency.
