Conditioners convert process-application signals

Rockwell has launched a line of signal conditioners for process applications that help users to isolate, convert and amplify analogue signals in applications involving batch or continuous processes.

The Allen-Bradley Bulletin 931 analogue signal conditioners range is comprised of 29 products that isolate multiple signals on the same power source, reducing ground-loop and common-mode noise.

By incorporating the conditioners into an existing control system, users can convert a range of signals from field devices into a standard 4 to 20mA 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 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 conditioners to help reduce additional I/O and cabling costs.

The signal conditioners convert thermocouple signals into the standard 4 to 20mA signal, which can be run over long distances on standard cable with less chance of signal deterioration.

Many of the Bulletin 931 analogue signal conditioners have hazardous-location approvals, including Atex and UL Class 1, Div 2 certification.

Transmission of data over the Hart Communication Protocol is available on certain models.
