 Omniterm LPI, LPD LPR and LPS DIN Rail Mount Current Loop Isolators

Instrument loop problems are frustrating at the best of times and can be really time consuming affairs to deal with. Most of the time these problems are related to isolation and ground faults. Thankfully, eliminating these problems is now quick and easy with the Omniterm LPI, LPD LPR and LPS DIN Rail Mount Current Loop Isolators. Utilising the latest electronic techniques to achieve extremely high accuracy with minimum loop losses and zero field calibration, these modules are designed to isolate instrument current loops from circulating ground currents, thereby preventing system inaccuracies and at worst instrument failures.

LPI & LPD Applications: Use the LPI to remove ground current loops in 4-20mA current loops where power is unavailable. LPD is a dual version, incorporating two LPI’s in a single 22.5mm housing, ideal for when space is at a premium.

LPR and LPS Applications: The LPR (Repeater) and LPS (Splitter) modules are specifically designed for applications where additional current loop signals are required from an existing current loop and are  designed in such a way that they have minimal effect on the impedance of the existing current loop.

Also use the LPR to increase 4-20mA drive capability or add additional instruments to an existing current loop. Use the LPS to create two independently isolated current loops from a single input loop or add instruments to an existing current loop.

Omniflex

The company was founded in 1965, formerly known as Conlog, specialising in process control, alarm/event management and instrumentation products and systems. In 1997, the original instrumentation business division of the company changed its name to OMNIFLEX Ltd.

The company was founded in 1965, formerly known as Conlog, specialising in process control, alarm/event management and instrumentation products and systems. In 1997, the original instrumentation business division of the company changed its name to OMNIFLEX Ltd.

Omniflex works across all business sectors including pharmaceuticals, hospitals, oil, gas, nuclear, water, electrical distribution and energy monitoring.

The company has its offices in the UK, South Africa, and Australia, and the company’s products are sold on five continents. Product ranges include well-known brands such as OMNI SIL alarm annunciators, OMNITERM SIL signal conditioning, MAXIFLEX intelligent remote terminal units (RTU) and I/O systems and the MAXILARM/Omni 4000 alarm/event management systems.

We bracket ourselves as a ‘remote monitoring specialist’, using data acquisition systems, with better than 1mS timestamp at the IO point (from several I/O up to thousands of I/O),  alarm event management including multiplexing systems, telemetry systems, Data2Desktop using standard web browsers, over varying forms of media and high-integrity (SIL1) annunciator systems.

A particular area that Omniflex is also very strong in is obsolescence issues on old legacy alarm annunciators systems. We have, in most cases, a solution for replacement of Rochester, Highland and Robinson’s annunciator systems. Our alarm annunciator systems have been substantiated by Sellafield for and on behalf of all the nuclear operators.

An area that we can offer customers significant cost savings is through the use of our CONET networking technology, which is supported by many of our RTU / PLC products. Using our CONET network technology allows existing installed cabling to be used therefore significant cabling/installation costs can be avoided. A typical example of this whereby our customer in the nuclear industry used our CONET technology, retained their existing cabling and infrastructure, saved them in the region of £1m on cabling and scaffolding.

As a worldwide supplier, OMNIFLEX provides technical training, back-up and application engineering support to a variety of industry partners including local distributors, value-adding resellers and systems integrators, to provide superior levels of service to the end user.
