Elsema: Top-Notch Wireless Transmitter and Receiver Solutions

Wireless remote transmission technologies are prominent fixtures in modern industrial and commercial automation. They eliminate the need for redundant and ultimately costly human intervention in tedious and potentially dangerous tasks. And to their credit, they can be engineered to perform a multitude of tasks at predictable rates and to a consistent standard every time.

The license free, 433MHz frequency band is where the most innovative advancements in remote controllable technologies are made. The development of low power devices (LPDs) using 433MHz band transmitters and receivers is reshaping how businesses are looking at cutting costs and increasing reliability on more of their core critical functions. The result is an overall increase in productivity, and not surprisingly a marked improvement in workplace safety.

Elsema’s Gigalink® Makes 433MHz Wireless Secure and Affordable

For more than 50 years, NSW’s Elsema has been on the leading edge of wireless remote control technology in Australia. It’s their latest generation of 433MHz wireless transmitters and receivers, however, that has made the biggest impression on Australian businesses. Their Gigalink® lineup of high performance, multi-channel wireless equipment, originally designed for gate automation, can be adapted to perform a virtually limitless range of industrial operations.

Any low power application that relies on core ON/OFF functionality can be adapted to utilise AS/NZS 4268-compliant Gigalink hardware, making automation an affordable alternative for all sizes of businesses and business processes. Wide area signal propagation and 32-bit digital encryption are the key features behind Gigalink’s micro-controlled GLR receivers and GLT transmitters. For businesses that want to leverage the benefits of low-cost wireless automation, that means operating distances of up to 350 metres, and as many as 4 billion possible code combinations for an array of applications, such as:

• ON/OFF mechanised conveyance and transport systems;
• Retractable bollarding, and automated security gate and barrier systems;
• Wireless traffic lighting, signalisation, and indicator activation systems;
• Remotely controlled and activated pumping and irrigation systems; and,
• Automatic, and wireless alarm and warning systems.

Whether it’s mining or manufacturing, or warehousing or construction, Elsema wireless systems offer the scalability that businesses of all sizes can use to automate almost any repetitive process. It’s Elsema’s commitment to simplified signal security though, that separates their Gigalink line of products from other wireless solutions. All of Elsema’s industrial-grade remote control systems, including their specialised GSM and PentaCode® lines, are designed with advanced-level encryption, but it’s their 433MHz wireless receivers that set the standard for affordable wireless signal security.

Wireless Encryption is the Priority for GLR Receivers

It’s a fact: without enhanced security, even the most advanced industrial wireless solutions are useless. Elsema, however, makes it easy for businesses to quickly ramp up a securely encrypted 240VAC wireless solution that uses only 2.2mA on standby, and is built to operate on Momentary, Latching, and Security Latching output modes.

Starting with their micro-controlled GLR wireless transmitter receiver, Gigalink does away with dip switch coding in favour of cable programming. This helps ensure instantaneous, straightforward transmitter and receiver programming, together with a host of technical advantages that include:

• Robust 32-bit digital code encryption;
• 1, 2, 4, and 8 multi-channel relay outputs with an unlimited number of programmable transmitters;
• A stable, two changeover relay output, rated at 8 Amps/240VAC
• Highly reliable crystal controlled carrier frequency tolerances; and,
• Greater than 1µV sensitivity for output activation.

And although GLR receivers are designed specifically to operate on a primary frequency of 433.920MHz, Elsema can custom program their GLRs to cover special frequency ranges which include:

• 433.664MHz (SF2);
• 433.408MHz (SF3);
• 433.152MHz (SF4);
• 434.688MHz (SF5); and,
• 434.432MHz (SF6).

Make no mistake: Gigalink’s GLR is one of the highest performing and most intuitive wireless receivers on the market. It also takes an equally high performing transmitter to take full advantage of what these receivers have to offer. This is where the range, reliability, and ultimately the security of Gigalink GLT transmitters becomes evident.

Maximum Multi-Channel Compatibility From GLT Transmitters

Rugged, Gigalink GLT transmitters are the perfect complement to the compact GLR receivers. With their lower 35mA power consumption, these 9V multi-mode transmitters are designed for continuous transmission for as long as a channel is activated. And where their greatest security risk comes from not having enough power to transmit, GLTs are outfitted with LED battery monitors that warn users anytime battery voltage drops below 6.5V.

With their 4 billion code compatibility, multi-channel GLT transmitters are optimal for environments where no-interference performance is crucial, and they’re available with a range of benefits that include:

• 1, 2, 4, or 8 button operation;
• The ability to be programmed to a corresponding number of receivers; and,
• Built-in loop antenna for continuous transmission.

GLT transmitters can also be programmed to match any of the special frequencies used by GLR receivers. They embody the flexibility and security that Gigalink wireless transmitters and receivers bring to every automated process.

The Final Word

At the end of the day, as the range of possible applications that high performance remote control systems continues to grow and evolve, so does the need for secure, scalable wireless signalisation. It has to remain cost effective though, and it has to be flexible enough to safely change with demands.

Whether it’s gate control on the approach to a transportation terminal, or activation of a linear or pivoting irrigation system, Elsema’s latest generation of 433MHz Gigalink transmitters and receivers have everything a business needs to economically automate its most basic operations. They’re a commitment to operational efficiency that businesses can’t afford to ignore.
