Instrumentation loop problems are frustrating at the best of times and downright time consuming affairs for plant maintenance staff to deal with: most problems relate to isolation and ground faults. Instrumentation loop problems are frustrating at the best of times and downright time consuming affairs for plant maintenance staff to deal with. Most problems relate to isolation and ground faults, some of which present themselves intermittently or are hidden so deep in the plant wiring that tracing them becomes a full time job. The Omniflex Omniterm range of DIN rail mount loop isolators use advanced electronic techniques to address the common problems associated with instrumentation loops using several specialised new products. The Omniterm LPI and LPX are current repeaters specifically designed to isolate instrument current loops from circulating ground currents that can cause system inaccuracies, or at worst instrument failure. The current applied to the input is repeated on the isolated output, and the load on the output is reflected back to the input. No separate power source is required. These second generation products utilise advanced electronic techniques to achieve high accuracy with minimum loops losses and zero field calibration.
The LPI is optimised for lowest volt drop over 4-20mA, while the LPX is optimised for use with an extended current range from 0-50mA and load impedances down to zero ohms. The Omniterm LPR current loop repeater and LPS current loop splitter products are specifically designed to create additional current loop signals from an existing current loop signal with minimal effect on the impedance of the existing loop.
The LPR has a single isolated output while the LPS has two isolated outputs.
These 24Vdc powered modules accept a 0-20mA or 4-20mA input and create 0-20mA or 4-20mA outputs. The output current loops repeat the input signal and are isolated from the input signal and 24Vdc power supply. Impedance changes on the output loops have no effect on the input loop. The module input is fully differential allowing the input to be connected anywhere in the input loop.

About: Omniflex
OMNIFLEX designs and manufactures electronic products and systems for the automation and control industry worldwide, specialising in industrial networking, remote I/O systems, process automation systems, signal conditioning, and alarm and event management.The company was founded in 1965 in South Africa and was originally named CONLOG, developing expertise in systems integration and product development for the process control and instrumentation market. The company's products are now sold on 5 continents and include such well known brands as OMNI16 alarm annunciators, MAXIFLEX process automation and remote I/O systems, and OMNITERM signal conditioning and RTU systems.
History.
Over the early years the company, under the CONLOG brand, grew to become the largest manufacturer of instrumentation for the process control industry in Africa and became a well respected designer and manufacturer of innovative products and systems of superior quality. In 1997 the CONLOG industrial products business was acquired by the present owners and the name of the company changed to OMNIFLEX. OMNIFLEX owns all of the intellectual property rights for the entire range of industrial products sold under the CONLOG brand and provides full technical and service support for all these products sold over the past 38 years. OMNIFLEX continues to market these products under the OMNIFLEX brand and continues to invest in research and development to maintain its state-of-the-art technology base.
Mission.
OMNIFLEX has as its core business, the design and manufacture of industrial automation electronic products and systems. OMNIFLEX has as its strategy the ongoing investment in research and development of electronic products for the control and instrumentation market globally. As a world-wide supplier of automation products, OMNIFLEX provides technical training, backup and application engineering support to a variety of locally based distributors and value adding re-sellers in order to provide superior levels of technical assistance to system integrators and end users in their own environment. |
