Rockwell Automation announces Bulletin 931 signal conditioners

　　Comprised of 29 distinct products, the Allen-Bradley Bulletin 931 analog signal conditioners mark the first Rockwell Automation components specifically designed for process applications.

　　The Bulletin 931 analog signal conditioners isolate multiple signals on the same power source, reducing ground loop and common mode noise. By incorporating the Bulletin 931 analog signal conditioners into an existing control system, users can convert a wide range of signals from field devices into a standard 4 to 20 milliamp signal. This helps users extend the performance and functionality of legacy control systems, improves design and integration flexibility, and mitigates the need for additional I/O purchases.

　　The signal conditioners are designed to help reduce time and costs associated with control system installations and upgrades for a diverse range of process applications. The signal conditioners can be integrated with the Rockwell Automation PlantPAx Process Automation System, leveraging a single control platform for discrete, batch, process, safety, drives and motion control.

　　Users with control systems that transmit thermocouple signals over significant distances can take advantage of the Bulletin 931 analog signal conditioners to help reduce additional I/O and cabling costs. The signal conditioners convert thermocouple signals into the standard 4 to 20 milliamp signal, which can be run over long distances on standard cable with less chance of signal deterioration.

　　Many of the Bulletin 931 analog signal conditioners have hazardous location approvals, including ATEX and UL Class 1, Div 2 certification, helping customers meet global standards to compete internationally. In addition, transmission of data over the HART Communication Protocol is available on certain models.
