Signal Isolators

Know more about Radix Signal IsolatorsWhat is a Signal Isolator?A Signal Isolator is an electronic device that transfers a signal from input circuit to output circuit while keeping the two circuits electrically isolated. Thus, it protects sensitive equipment from ground loop problems, noise and voltage surges, while ensuring accurate signal transmission.Signal Isolators are also known as Signal Converters and Signal Conditioners.Our Range of Signal IsolatorsRadix manufactures a wide variety of Signal Isolators and Signal Converters for every industrial application. These include isolators with single and multiple inputs, single and multiple outputs, isolators for temperature, linear inputs, powerline voltage and current, loop-powered devices and more.The signal isolators from Radix are designed for reliable signal isolation, accurate measurement and conversion of very small signals, and signal conditioning across a wide range of industrial applications. The Radix range of Signal Isolators includes analog isolators with field-adjustable settings as well as microcontroller-based digitally configurable isolators, offering flexibility to suit diverse process requirements. Models are available with communication protocols such as RS485 Modbus RTU. One particular Signal Isolator (model SCC312) has a display as well as relays for alarm purposes. Another model (SCC335) has 5 isolated outputs.The signal isolators most commonly used are: signal isolator, 4-20mA (or signal conditioner, 4-20mA); thermocouple signal conditioner; universal input signal conditioner; Some of these are described as analog signal conditioners, and use an analog signal conditioning circuit. Other signal conditioners (signal converters) use a combination of microprocessor and analog circuits for flexibility and signal conversion, e.g. linearisation.Our Signal Isolators can also be supplied with a test certificate from our in-house accredited NABL (National Accreditation Board for Testing & Calibration Laboratories) Test Laboratory.How Signal Isolators Are UsedThe most common application of a signal isolator is to prevent electrical noise - both radiated and conducted, from interfering with measurements of process signals. The second common application is to protect sensitive and expensive downstream equipment such as PLCs and DCS from getting damaged due to surges and spikes.Every Radix Signal Isolator uses a precision signal conditioning circuit comprising optical and magnetic signal isolation and conversion. High resolution ADCs which measure signals up to 21-bit resolution and low-drift amplifiers are used.In many cases, the signal converter - also known as a signal conditioner - processes the input signal, e.g. by linearisation of a (non-linear) thermocouple signal into a temperature-linear 4-20 mA or 0-10V output signal.Benefits of Signal IsolatorsDesigned for performance, Radix isolators provide high accuracy, fast response times (down to 500 µs in certain models), and strong galvanic isolation up to 3,000 V AC, ensuring reliable operation in electrically noisy environments. They effectively protect expensive equipment against ground loops, voltage surges and interference, improving overall system stability.Signal Isolators - ApplicationsWith their combination of compact design, flexibility, and high reliability, Radix signal isolators are widely used in various industries : <ol><li data-list="bullet">Process industries</li><li data-list="bullet">Power and Energy systems </li><li data-list="bullet">Water treatment </li><li data-list="bullet">Manufacturing automation </li><li data-list="bullet">HVAC</li><li data-list="bullet">Battery manufacturing</li><li data-list="bullet">OEM equipment panels where dependable signal interfacing and isolation is essential.</li></ol>Our Manufacturing FacilityThis full range of Signal Isolators and Signal Converters is manufactured at our modern, well equipped manufacturing facility in Navi Mumbai.
